Silicon Nitride Si3n4 Ceramic Igniter Electric Heating Element for Industrial Heating Equipment

Product Description

 

Silicon Nitride Ceramic Electric Heating Element

 

The characteristics of silicon nitride ceramic electric heating element:

This product uses the high-performance silicon nitride ceramic substrate, high temperature, and high

 

mechanical strength, thermal shock resistance is strong, resistant to acid and alkali corrosion, both with

 

excellent insulation properties, and good thermal conductivity, combined with the company's proprietary

 

formula and the hot pressing manufacturing technology.
