Product Description:
Silicon Nitride (Si3N4) is a widely used ceramic material in high temperature application, it has high strength in both room temperature and high temperature condition.
The strength of silicon nitride can be kept up to 1200ºC; the low coefficient of thermal expansion make it a ceramic material possessing excellent thermal shock resistance; at the same time, it also has good thermal conductivity.
Except for the excellent properties in thermal application, silicon nitride also has good mechanical, chemical, electrical properties.
It has good strength, good flexture strength and wear resistance;it is a good performance electrical insulation ceramic material; it is corrosive against all inorganic acid, most of organic acid solutions and some of caustic soda solutions.

2.Where is your main market?
We have been exported to USA, Korea, UK, France, Russia, Germany, India, Spain, Brazil etc, so far, there is about 151 countries we have been exported, we also get good reputation from our customers.
3.What about the package?
We pack with plastic bubble paper, carton box, then safe wooden box outside, we can control the breakage less than 1%.
4.Do you support OEM?
Sure! We offer OEM for many customers all over the world.
5.Will your company supply wooden wicks samples?
Yes,we do.The sample expense will be deducted from the value of your order.
6.How long is the delivery time?
For the standard products,like ceramic substrate and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30-45 working days.
