Silicon nitride ceramic substrate mirror polishing

Silicon nitride is a man made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.

   Silicon nitride exceeds other ceramic materials in thermal shock resistance. It also offers an excellent combination of low density, high strength, low thermal expansion and good corrosion resistance and fracture toughness.

   Silicon nitride has been used in a number of industrial applications, such as engine components, bearings and cutting tools.

Shenzhen Hard Precision Ceramic Co., Ltd is a company dedicated to the professional fine ceramic manufacture. We specialize in the design and manufacture of aluminum oxide,zirconium oxide and silicon nitride ceramic product. The main products include Ceramic Plungers,Ceramic Ball Valves,Ceramic rods,Ceramic Nozzles,Ceramic Plates and other Industrial Ceramic Products.

HARD develops fine ceramic products which are widely used in machinery, semiconductor, aerospace, petroleum, chemical, electronics, medical, fluid control, food and other industries. The superior electrical characteristics of fine ceramics are utilized in a variety of circuit boards and electronic parts. Their wear and corrosion resistance is beneficial in pumps nozzles and valve parts, and their high heat and thermal shock resistance is useful in ceramic engine parts.

Compared with the advanced ceramic and metal, with high hardness, high strength, high temperature, wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, nonmagnetic, good chemical stability and other excellent performance.

We have a full service include ceramic forming,mold design and development,precision machining and precision detection technology, and our technician have many years of experience in ceramic processing. We can provide a full set of ceramic solutions for customers, and can make different kinds of ceramic products according to customer's special request.
