Product Description

Product Description

 

Steatite ceramic parts

 

Steatite ceramic rods,poles,shafts,bars

 

Steatite is made of mineral talc (3Mgo 4Sio2 H2O) as the main raw material, adding appropriate amounts of clay, BaTi03 and other ingredients, and mixing and grinding, molding and high temperature sintering. Used for insulating parts.

 

Chemical component:

SIO2: about 60%
MgO:about 31%
AL2O3:about 5%
BaO:about 5%
CaO:about 0.5%
Fe2O3:about 0.2%

Physical Properties
* High electrical resistance
* Low dielectric loss factor
* Relatively high mechanical strength
* High volume resistivity at elevated temperatures
* Excellent dielectric strength
* Low dissipation factor

Applications
* Insulating washers or bushings
* Supports for heating elements
* Electrical insulators
* Stand-off insulators
* Lighting insulators (supports, bases, etc.)
* Spacers
