ZIRCAR Ceramics’ Alumina Mat is a lofty, layered, low-density flexible mat made of 100% polycrystalline alumina fiber, designed for use to temperatures as high as 1650°C (3002°F). ZIRCAR Ceramics’ Alumina Mat is a lofty, layered, low- density flexible mat made of 100% polycrystalline alumina fiber. It is light in weight, contains virtually no shot and is designed for use to temperatures as high as 1650°C (3002°F). Alumina Mat’s high-purity aluminum oxide fibers exhibit lightweight, low-thermal conductivity, low-thermal mass and immunity to thermal shock. A minor addition of silica modifies the fiber’s microcrystalline structure which inhibits unwanted grain growth. This prevents embrittlement that usually occurs after extended use at elevated temperatures. Alumina Mat is not affected by oil or water and resists attack in numerous aggressive chemical environments. It is stable in vacuum, inert or reducing atmospheres. It is however affected by hydrofluoric acid, phosphoric acids and strong alkalis.
