Silicon Carbide Saggars

Introduction:
The silicon carbide saggar has a large loading capacity and stable loading,which can make full use of the space of the kiln and kiln cart,increase the output value and reduce energy consumption.The heat conduction of the product is great,and the comprehensive production capacity has been improved.

Features:
1.High strength.
2. Good thermal conductivity.
3.Good thermal shock stability.
4.Good wear-resistance performance. 

Application:
It is widely used for sinter powder and ceramic.It has very good performance in high temperature furnace.
