we are famous ceramic ball valve and ceramic structural parts manufacturer in china.

the silicon nitride ceramic production pressure sintering technology, with high hardness, high strength, self lubrication, corrosion resistance, anti-oxidation. but it can also resist the impact of hot and cold, the air is heated to 1000 centigrade, rapid cooling and rapid heating, no fragmentation, is structural ceramic materials high temperature, thermal impact working conditions and mechanical properties of the ideal.

our company produces ultra precision silicon nitride ceramic ball valve, the roundness of less than 2 microns, to a mirror like surface roughness, reached the highest accuracy level within the industry.

silicon nitride balls can be obtained by direct reaction between silicon and nitrogen at temperatures between 1300 and 1400, some of the advantages of silicon nitride balls are fine crystalline they never rust, and can roll without oil or grease. silicon nitride is a chemical compound of silicon and nitrogen. it is a hard ceramic having high strength over a broad temperature range, moderate thermal conductivity, low coefficient of thermal expansion, moderately high elastic modulus, and unusually high fracture toughness for a ceramic.

this combination of properties leads to excellent thermal shock resistance, ability to withstand high structural loads to high temperature, and superior wear

resistance. silicon nitride is mostly used in high-endurance and high-temperature applications, such as gas turbines, car engine parts, bearings and metal working and cutting tools.

silicon nitride bearings are used in the main engines of the nasa's space shuttles. thin silicon nitride films are a popular insulating layer in silicon-based electronics and silicon nitride cantilevers are the sensing parts of atomic force microscopes.

silicon nitride balls are used in processing equipment to improve bearing performance. silicon nitride balls are lighter, stiffer, smoother, harder, corrosion resistant, require less lubrication, and have a lower thermal expansion than their steel counterparts which allow the bearing to run at higher speeds and higher operational temperatures with lower torque. silicon nitride balls are better in oscillation, extreme temperature and are extremely durable.
