Ceramic Parts

Silicon carbide (SiC) is a structural ceramic material with excellent properties. Silicon carbide parts, that is, equipment parts with silicon carbide and its composite materials as the main materials, have the characteristics of high density, high thermal conductivity, high bending strength, large elastic modulus, etc., and can adapt to the harsh reaction environment of strong corrosiveness and ultra-high temperature in wafer epitaxy, etching and other manufacturing links, so it is widely used in major semiconductor equipment such as epitaxial growth equipment, etching equipment, oxidation/diffusion/annealing equipment.

① Aluminum oxide is an important type of oxide ceramic, widely used in precision components of semiconductor equipment, wafer polishing processes, aerospace fields, automotive industry, and medical device industry, etc.

② Depending on the crystal structure, aluminum oxide can be divided into α-alumina, β-alumina, γ-alumina, and δ-alumina.

③ Currently, the purity of aluminum oxide ceramics on the market generally includes 95%, 99%, 99.5%, 99.7%, 99.9%, and 99.99%. For example, the highest purity aluminum oxide ceramic targets are used in the preparation process of semiconductor integrated circuit chips. 

① Boron carbide ceramic is a ceramic material composed of carbon and boron elements. It has many unique properties that make it widely used in various fields.

② In the civilian field, boron carbide ceramic is commonly used in engineering ceramics and wear-resistant technology, making boron carbide ceramic products such as boron carbide nozzles widely used in daily life and in industrial and agricultural production.

③ In the nuclear industry, boron carbide's excellent thermal neutron absorption capability makes it a control rod, regulating rod, accident rod, safety rod, shielding rod, and is used in the production of boron carbide tiles and plates for radiation protection.

④ In the military field, boron carbide ceramic is widely used in bulletproof vests, bulletproof armor, armed helicopters, and special vehicles for police and civilian use, making it the best material for bulletproof vests, helmets, and armor. 

Boron nitride ceramic is a new type of inorganic non-metal material with a flaky structure, obtained by hot pressing sintering of boron nitride and composite material powders, and it possesses special physical and chemical properties as a hexagonal crystal system. Due to the high-temperature and high-pressure sintering of boron nitride powder, its appearance is white, commonly known as "white graphite".  Boron nitride can maintain its structural integrity and mechanical properties under extreme high-temperature conditions. Boron nitride can resist oxidation up to 900°C in the air, and its sintering temperature can reach 2000°C under vacuum conditions.It can be used as crucibles, boats, and liquid metal transportation pipes for melting and evaporating metals, rocket nozzles, and bases for high-power devices. It is widely used in electronic packaging and thermal management materials, such as thermal interface materials, insulating ceramics, and high-frequency electronic components. 

Alumina ceramics are special ceramics made of Al2O3 as the main raw material, rare metal oxides as fluxes, and roasted at a high temperature of more than 1,000 degrees. The product has the characteristics of wear resistance, corrosion resistance, heat resistance, impact resistance, high hardness, high voltage resistance, insulation and heat conductivity.
