Frequently Asked Questions
What is the difference between soapstone and talc?
Both share the same formula but soapstone is the massive, compact form. Its denser structure makes it ideal for ceramics and electrical insulation.
Is soapstone heat resistant?
Yes. Soapstone withstands temperatures above 1000°C, ideal for refractory applications.
Can soapstone be used for electrical insulation?
Yes. Steatite ceramics from soapstone are widely used for electrical insulators.
