精密陶瓷
精密陶瓷發展至今已經被廣泛應用，在我們每天在用的水龍頭中，水龍頭的閥心就是使用精密陶瓷，一般是使用95%氧化鋁，如果比較高級的衛浴設備會使用常壓燒結碳化矽(sintered silicon carbide)，常壓燒結碳化矽的使用壽命高出一般的陶瓷數倍。

精密陶瓷( Fine Ceramics )有別於傳統陶瓷，是採用精製高純度無機材料做為原料，用化學及物理方式控制組成及均勻度，再用乾壓、鑄漿或射出等成型方法，再經由反應或燒結使其顯微結構、化性及物性達到另一個水準，最後經過加工形成具有卓越性能的產品；精密陶瓷具有六大特性：
一、耐腐蝕
大部分陶瓷皆具有抗氧化及耐化學腐蝕的能力。
二、耐高溫
很少有其他材料可以與陶瓷材料所承受高溫比擬，某些精密陶瓷( Fine Ceramics )可承受高溫1400°C仍保持強度，但像是最耐熱的超合金卻很少可用於超過1100°C的溫度。
三、耐磨耗
精密陶瓷(Fine Ceramics )耐磨耗能力是大家眾所皆知的。
四、重量輕
大部分陶瓷都比金屬輕，甚至可能達金屬的40%，因為重量輕可以減輕機械的負擔，並節省能源。
五、摩擦係數低、高壓縮強度
精密陶瓷( Fine Ceramics )因低摩擦係數及高壓縮強度與耐磨阻力，使有些精密陶瓷用於軸封、軸承等機械元件中不需潤滑。
六、電磁光熱特性
某些精密陶瓷( Fine Ceramics )具有較特殊電、磁、光、熱特性。
精密陶瓷( Fine Ceramics )雖擁有這些優良特性，但其低韌性(高脆性)容易造成使用者困擾，所以敝公司積極努力研發韌性較高的精密陶瓷( Fine Ceramics )。

Zirconia Oxide - silicon carbide | sintered silicon carbide | alumina oxide | fine ceramics | zirconia oxide | pump | pumps | pump ceramics | pumps ceramics
Except inheriting the special characters (high strength, high hardness, thermo-endurable capability, anti-chemicals and high chemical stability) of fine ceramics, zirconia also owns better tenacity than ordinary ceramic materials, which enable zirconia to be applied in many industries, such as the production of spindle seals and bearings, cutting tools, molds, and vehicle parts, etc.; it also can be applied for medical applications, such as being the artificial hip joints of human body and similar.
Zirconia material can be categorized into the following four sorts:
1. Fully stabilized zirconia (FSZ)
Formed by complete cubic lattices structure; poor in mechanical properties.
2. Zirconia toughened ceramics (ZTC)
Compound of the 2nd phase and other materials (Al2O3, Si3N4 and glass, etc.); the tenacity and mechanical properties are improved.
3. Partially stabilized zirconia (PSZ)
PSZ is the sort of zirconia material we are producing now; PSZ is made by adding Y2O3 into the zirconia structure base that will make the square lattice phase distributed in the cubic lattice phase; through the phase-change of square lattice phase, the zirconia organization would obtain higher tenacity and thus toughen the PSZ property.
4. Tetragonal zirconia polycrystals (TZP)
TZP is made by adding Y2O3-ZrO2 into the zirconia base, which can get better mechanical properties, higher strength, tenacity and chemical stability; it is widely applied in structure and medical applications.

Alumina Oxide - Sintered Silicon Carbide | Silicon Carbide | Fine Ceramics | Zirconia | Alumina Oxide | Pump
The global storage capacity of alumina oxide is the one second to silicon oxidation only; it is a component of raw ceramic material. In alumina oxide molecule, aluminum atoms hold strong chemical bonds to oxygen atoms, which form extremely high hardness among its oxides. And the stable chemical properties make the alumina oxide in high corrosion resistance to most acids, alkalis and chemicals as well as melted solutions. The structural strength of Al2O3 is influenced by its density and microstructure; in normal temperature condition, it holds the highest strength; when the ambient temperature rises up to 1000˚C, the material structure decays apparently. Also, the Al2O3 holds relatively lower thermo-expansion coefficient.
The properties (thermal, mechanical, physic & chemical one, etc.) of Al2O3 are all relevant to its purity contained in the base organization.
Generally speak, the higher alumina oxide purity the material holds, the better thermal conductivity it behaves; when an extremely high alumina oxide purity reaches, the material¡¦s specific density will approach its theoretic one and earns excellent mechanical properties in response.
Nowadays, vendors have massively applied alumina oxide to replace metallic parts in the prospective of improving the properties of anti-corrosion, anti-wear, thermo-endurable capability and strength-enhancement. For now, not only the high-tech semiconductor vendors massively apply alumina oxide-based ceramic devices, other industries also gradually use this ceramic material to improve product properties, elevate efficiency and reduce cost.

Fine Ceramics - Sintered Silicon Carbide | Silicon Carbide | Alumina Oxide | Zirconia | Fine Ceramics
We select high-purity inorganic materials to produce fine ceramics under the dry-pressing, casting or injection process, by physic or chemical procedure, to control the compounds and uniformity of products; and we conduct the product’s microstructure, physical & chemical properties to an advanced base organization standard through reaction or sintering process. In the last process, we machine the products and create excellent performance for application. The fine ceramics feature the following six characters:
1. Anti-corrosion
Most ceramic products own strong anti-oxidation and anti-chemical-corrosion capabilities.
2. High temperature endurable
Rare materials can withstand the very high temperature as a ceramic material does; some precise ceramic products can literally endure a working temperature as high as 1400°C and still hold its strength unchanged, whereas the best super alloys can hardly withstand a work temperature of over 1100°C.
3. Anti-erosion
The anti-erosion capability of precise ceramic materials is the feature widely aware by the industry.
4. Light in weight
Most ceramic materials are lighter than metals; some of them even are 40% lighter than metallic one; light weight is favorable to lower machine’s loading and save operating energy.
5. Low friction coefficient and high compression strength
The remarkable low coefficient, high compression strength and anti-friction features of fine ceramics make them pretty suitable to be used as mechanical wearing devices, such as spindle seals or bearings, without the need of lubrication.
6. Electrical, magnetic, light and heat characters
Some fine ceramics own special electrical, magnetic, light or heat characteristics.Although fine ceramics obtain the aforesaid excellent characters, however, the vulnerable low tenacity (brittle) always confuse the ceramic product’s users; to solve this vulnerability of ceramic materials, we have already made great endeavor to develop the high-tenacity precise ceramic materials.

Sintered Silicon Carbide Introduction | Sintered Silicon Carbide | Silicon Carbide | Fine Ceramics | Alumina Oxide | Zirconia | 碳化矽 | 氧化鋁 | 氧化鋯 | 精密陶瓷
Nowadays, customers are used to apply silicon carbide as the non-oxidation ceramic material; the silicon carbide owns better hardness, heat-resisting, anti-oxidation, anti-corrosion and high thermo conductivity than ordinary ceramic materials. Recently, the silicon carbide material is widely applied in mechanical structures and chemical seal parts; it is applied in extreme harsh working environments such as under strong acid, alkali, heavy wear, high temperature or aviation & space traveling conditions.
Sintered silicon carbide (S-SiC):
The sintered silicon carbide (S-SiC) products are our major products supplying to market.
The sintered silicon carbide (S-SiC) material has a mechanical performance similar to the HP-silicon carbide (HP-SiC) material; yet, its workmanship is superior to HP-SiC and cheaper in production cost, suitable to mass production or products with complicate shapes. The S-SiC completely meets the requirements of producing mechanical seals and parts of spindle-seal-free pumps (shielded pumps) or magnetic pumps; sintered silicon carbide (S-SiC) now is the silicon carbide ceramic material so popular in overseas industries.
The sintered silicon carbide organization is formed by £\-SiC crystals; the volumetric density can reach over 98% (3.1g/cm3) of its theoretic one. Its density is 1/5 of tungsten carbide, and hardness is only second to diamond, performing extremely excellent efficiency in anti-grain-wear practice. So far, the combination of sintered silicon carbide (S-SiC) and graphite is the seal pair with the highest PV value in application. The high-purity sintered silicon carbide (>98% silicon carbide) can withstand chemical corrosion of various kinds under high temperature condition. The sintered silicon carbide bears extremely high specific strength; and its anti-oxidation capability and mechanical properties under high-temperature status are excellent as well.
