Produced according to ASTM standard

Advantages
Excellent strength at ambient and elevated temperatures
High compressive strength
Every brick ground to precise dimensions
Lightweight, energy-saving nature results in less heat loss, lowers operating costs, and allows for thinner furnace linings

Lower heat storage than dense refractories
Heats quickly and economically to kiln's operating temperature
Cools fast to speed periodic operations
Very low levels of iron and other impurities (especially resistant to tough, reducing atmosphere conditions)
Available in custom designed shapes upon request.
