Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. It is also resistant to thermal shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is precisely because of the excellent properties of Si3N4 ceramics that it is often used to make bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the silicon nitride ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of engine parts, not only can the diesel engine quality be improved, fuel can be saved, but thermal efficiency can be improved. China, the United States, Japan and other countries have developed such diesel engines.
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.

SHENZHEN HARD PRECISION CERAMIC CO.,LTD
Shenzhen Hard precision ceramics Co., LTD. has been committed to design, development and manufacture of industrial ceramic products since 2007. Compared with metal, advanced ceramic has the following excellent performance: high hardness, high strength, high temperature (fire), and can wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, non-magnetic and good chemical stability . So it is often used in the environment where the metal material cannot endure. With its promising application , advanced ceramics are widely used in aerospace, aviation, military industry, nuclear power, machinery, textile, chemical, electronics, food, medical and other industries. Our advanced ceramic products made by zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products can divide into two parts: one part is ceramic ball, rods, tubes, ceramic materials such as plate, block, strip and so on, and the other part is the precision ceramic parts which are for industrial use and civilian products. Our company has advanced one-stop equipment and technology of ceramic forming, sintering and processing. Hope we can establish excellent cooperation with customers from at home and abroad for a wide range .
