Also known as Macor, these glass-mica ceramic sheets and bars withstand temperatures up to 1470° F.

One of the few known materials that both draw heat away from hot spots and block electrical currents, aluminum nitride ceramic sheets are great for heat sinks and other electronic components.

Sintering creates strong inner bonds, making this version of silicon carbide more resistant to wear and chemicals than other forms of silicon carbide as well as most ceramics.

These sheets are often used as shelves and supports in unsealed kilns or as a lining in metal processing equipment. They withstand high heat without sacrificing strength, thermal shock resistance, and chemical resistance.

Made of nearly pure silicon carbide, these sheets resist creep more than other ceramics and are consistently strong throughout, so they won’t sag under heavy loads at high temperatures. Because they withstand extreme temperatures, they’re often used as kiln furniture and machined into structural furnace components.
