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%
