  • Refractory Standards - ASTM

    ASTM's refractory standards are instrumental in specifying, testing, and evaluating the chemical, physical, and mechanical properties of various materials and products made of refractory. These materials, which are commonly made from the oxides of aluminum (alumina), silicon (silica), magnesium (magnesia), and calcium (lime), have the distinct characteristic of being able to retain physical and chemical stability at extremely high temperatures.

  • Refractory and high temperature insulation materials

    In general, refractory materials are ceramic materials that are used permanently at temperatures above 600°C. The materials are grouped in oxidic or non-oxidic refractory materials. Oxidic materials are mostly based on SiO 2, Al 2 O 3, MgO, CaO, ZrO 2 and Cr 2 O 3. The most important non-oxidic refractory materials are carbon or carbides and nitrides for special applications.
