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.
