ELECTRICAL PORCELAINS

Kyanite and mullite are used in many electrical types of porcelain because of their high thermal resistance and extremely low electrical conductivity. Kyanite was first used in industrial applications during WWI as the electrical insulator. Today Virginia Kyanite™ is commonly used in many electronics – from electrical insulators to spark plugs. Virginia Mullite™ is even being tested as a possible alternative material in the manufacture of electrical substrates.
