the following example is for you reference.


1.Brief Introduction:

  

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.

2.Techincal parameters:

Physical Property and Index:

Types	Data
Density	>3.2g/cm3
Flexural strength	800-1200Mpa
Compressive strength	>1500Mpa
Thermal conductivity(W/mk)	16-22
Porosity	0
Thermal expansion coeff.(RT-1000)	3.2
Max temperature in air	1200
Hardness(HRA)	>92

3.Performance features:

Features:

1.Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions.

2.Lightweight Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration.

3.Superior Surface Finish, Ra 0.1 7-0.25 micro inches may extend L-10 life to as much as 10 times that of steel bearings.

4.High Temperature Hardness is twice that of steel. these all-ceramic balls retain their strength and hardness up to 1800 degrees F.

5.Silicon Nitride is further characterized by its low density of 3.2 g/cc, high flexural strength of 1.0 GPa, and fracture toughness of 6 MPa/M2.
