Si3N4:
1, corrosion-resistant strong acid, alkali, seawater can also be used.
2, high temperature, ultra-wear-resistant, silicon nitride ceramic ball at 8000C, the strength,
hardness almost unchanged.
3, non-magnetic, insulation, magnetic field can also be used, non-conductive.
4, light weight, lighter than the average material bearing 1/4, the density of 3.20g / cm3.
5, high rigidity, high strength, the hardness of the bearing than the double, elastic
modulus of about 1/3.
6, high-speed rotation, rotating body (ball) light weight, small centrifugal rotation.
7, silicon nitride ceramic ball linear expansion coefficient of 3.2 Ã? 10-6 / K, almost
1/4 of bearing steel.
8, silicon nitride ceramic ball bearing self-lubricating can solve the lubrication caused
by pollution and add inconvenience.
9, drug resistance, mechanical strength, damage toughness, low thermal conductivity.
Application areas: composite bearings, mechanical seals, chemical pumps, nozzles,
auto parts, heat exchanger parts, vacuum equipment and other harsh environments.

GRADE
G5-G25
PERFORMANCE
1,59% lighter than the ball, which means less centrifugal force and wear less groove at high speed and acceleration.
2, 44% of the modulus of elasticity, which means less load deformation.
3, Rockwell hardness 92
4, the smaller the coefficient of friction
5, only 1/4 of the thermal expansion coefficient of steel, you can tolerate high temperatures.
6, can achieve excellent surface finish, Ra can be 4 to 6.
7, can withstand high temperature and high hardness and strength up to 1050 ° C
8, never rust, can be no lubricant. The
9, more resistant to corrosion than steel.
APPLICATION
Silicon nitride ceramic ball can be used for a variety of bearing performance requirements: high-speed / ultra-high-speed bearings, high precision bearings, vacuum bearings, high / low temperature bearings, non-magnetic bearings, high precision ball screw; , High temperature pump, metering pump used as a ball, measuring the ball.

Si3N4 Ceramic Substrate Manufacturer,Silicon Nitride Ceramic For IGBT,Power Module Substrates,LED Substrate Product Description Silicon Nitrides (Si3N4) Feature An Excellent Combination Of Material Properties. They Are Nearly As Light As Silicon Carbide (SiC), But Their Microstructure Gives Them Excellent Thermal Shock Resistance And Their High Fracture Toughness Makes Them Resistant To Impacts And Shocks. Properties Of Silicon Nitride (Si3N4) Very Low Density (3.21 G/Cm3) Very High Fracture Toughness (7 MPam1/2) Good Flexural Strength (850 MPa) Very Good Thermal Shock Resistance: High Thermal Stress Parameters (569 K) Maximum Operating Temperature In An Oxidizing Atmosphere: 1,300°C Maximum Operating Temperature In A Neutral Atmosphere: 1,600°C Feature High Strength (High Reliability) Similar To The Thermal Expansion Coefficient Of Semiconductors Such As Si, SiC, And GaN High Dielectric Strength High Bending Strength Main Use Of Precision Ceramics For Electronics (Si3N4=Silicon Nitride) Power Module Substrates LED Substrates Submount For Optical Pick-Up Heat Dissipation Substrates The porous silicon nitride ceramic material combines the excellent properties of both the silicon nitride ceramic and the porous ceramic and is a ceramic material having a communicating or closed pore in the body. Porous silicon nitride ceramics have been widely used in aerospace and environmental chemicals due to their special structure and properties, such as low density, high porosity, moderate dielectric properties, high specific surface area, high hardness, and high fracture toughness. Important fields such as biomedicine, national defense, and military.
