Applications

Mica is used as a thermal and electrical insulator in induction furnace coils, helping prevent arc damage and improve energy efficiency.

Mica-based liners and pads provide thermal barriers in ladles and tundishes, extending equipment life and maintaining steel temperature control.

Mica parts insulate critical components in arc furnaces, annealing lines, and heat treatment stations to protect against short circuits and heat damage.

Mica components act as anti-stick, heat-resistant barriers in molds and casting dies, improving part finish and reducing downtime.

Mica’s optical clarity and heat resistance make it ideal for high-temperature sight windows in furnace doors and observation ports.

What is Mica

Mica is a naturally occurring mineral, based on a group of silicate minerals composed of varying amounts of aluminum, potassium, magnesium, iron and water having thin sheet-like or plate-like structure with different composition and physical properties.
