Steatite Ceramic Insulator for Band Heater
1. Brief Introduction
Steatite is lower in cost than Alumina but offers reduced mechanical properties. However Steatite has very good electrical resistance properties, which are retained at high temperatures, along with moderate mechanical strength and temperature resistance. It has been used in electrical insulation for many years in both large-scale electrical systems and electronic and domestic appliances.
2. Characteristics
1. High resistivity
2. Moderate strength
3. Excellent electrical properties
4. Poor heat conductivity (Thermal insulator).
5. Good resistance to thermal shock.
6. Low coefficient of thermal expansion.
7. Good mechanical stability.
3. Parameter.
