Description

Product characteritics

Silicon Nitride material is one of the hardest materials in the world with extrusion molding process and hot isostatic pressing sintering adopted during the production. Its high strength, wear resistance, temperature resistance, corrosion resistance, acid resistance and alkali resistance can well ensure the purity of materials.

Application

It is a precision ceramic sintered at high temperature in a non-oxidizing atmosphere. It has five properties, high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance. So it can be used in seawater for a long time. It also has self-lubricating properties, and it can be used in environments with high pollution of non-lubricating media.

Advantages of Silicon Nitride Bearing balls:

Properties Ordinary Steel Ball Silicon Nitride Balls Evaluations
Density(kg/cm3) 7800 ≥3220 The lower the density, the less energy loss
Young's Modulus (GPa) 210 ≥300 The higher the modulus number, the smaller the deformation
Vickers-hardness(GPa) 8 14-18 The higher the hardness, the better the rigidity
Toughness (MPa·m) 16-25 6-8 The higher the toughness, the better the impact resistance
Thermal Expansion Rate(10-6/K) 12 ≤3 The lower the thermal expansion rate, the smaller the deformation
Specific Heat Capacity(J/kg·K) 450 650 The larger the specific heat, the smaller the temperature change
Use Upper Limit Temperature(℃) 230 1000 The higher the online temperature, the wider the application field
Minimum Surface Roughness(μm) 0.02 0.004-0.005 The smaller the surface roughness, the smoother
Compressive Strength (MPa) 7.5 ≥3000 The higher the compressive strength, the longer the life
Resistivity (Ω·cm) 0.001 10^14 The higher the resistivity, the better the insulation
