Ceramic Advantages
1). Strong acid resistance
2). Strong insulation
3). Strong adsorption
4). High thermal insulation performance
5). Chemical stability
6). High compressive strength
Steatite ceramic base (also known as soapstone ceramic base) is a cost-effective, insulation-focused component made from steatite (a magnesium silicate mineral, Mg₃Si₄O₁₀(OH)₂) as the core material. It is engineered for excellent electrical insulation, stable thermal performance, and easy machinability, making it widely used as a mounting or supporting base for electronic components, heating elements, and electrical devices.
