Silicon carbide, specifically reaction bonded and self-sintered silicon carbide, offers superior strength, abrasion resistance, and thermal conductivity to alumina ceramic.
Reaction bonded silicon carbide is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming silicon carbide. The reaction product bonds the silicon carbide particles. Any excess silicon fills the remaining pores in the body and produces a dense SiC-Si composite.
Sintered silicon carbide is a premium version of silicon carbide. It contains no free graphite or silicon. Sintered silicon carbide is Waukesha's hardest seal face for sanitary pumps. It contains no silicon that can leach into the process, is excellent in an oxidizing environment, and has good thermal shock resistance due to low thermal expansion coefficient and high thermal conductivity.
In summary, silicon carbide's combination of hardness, strength, and temperature resistance gives it excellent capabilities for services in a wide range of applications where high speeds, high pressures, and chemical and abrasion resistance are required.

Customized Heterotypic Technical Ceramics
AIZA is a Lianyungang based Sino-Foreign joint venture corporation. It is a Chinese producer of calcined alumina and a manufacturer of alumina ceramics, such as alumina ceramic ball, alumina ceramic cylinder, alumina wear tile, ceramic insulator, ceramic element, ceramic beads, and other insulation ceramics with self-prepared material as well as German and Japanese material.
Since its creation, AIZA has served most of Chinese customers, Nanjing Huade, Zhuzhou Xianghuoju, and Chaozhou Sanhuan, which are eminent manufacturer of spark plug and advanced ceramic in China. Its "TCH" brand calcined alumina is well accepted by our customers.
In 2008, AIZA purchased 70 key equipment from Shanghai Morgan Matroc after its closure in China. The equipment includes isostatic press machine, dry press machine, hot press cast machine, ball mill, alumina spray prilling tower (centrifugal and pressure), polishing machine, etc. The equipment has been successfully installed in our factory by the end of 2008. Now, AIZA have succeeded in establishing itself as sole Chinese manufacturer of ceramic nozzle by isostatic dry bag pressing process. Besides, the most experienced technical engineer of former Shanghai Morgan Matroc also joined us, which is the precious source of our confidence of ensuring products quality.
