magnesium oxide ceramic is a highly chemically resistant insulator that offers high thermal conductivity and fire resistance. Its typical uses include cartridge heaters, thermocouples, mineral insulated cable, and high watt density heaters.
MgO ceramic is a full-fired, 99% pure material with a high-density fine grain microstructure and open porosity of less than 1%. It is ideal for processing refractory metals, slags and superconductor compounds up to 4000degF.
It is an alternative to alumina for applications requiring greater corrosion resistance. It is also an excellent choice for refractory brick, especially in steel and other ferroalloy manufacturing industries.
Using MgO Strategies to Reduce Glaze Crazing
As discussed earlier, MgO is an extremely valuable lowering agent for the thermal expansion of glazes (especially when replacing calcia, baria, and zinc). Because MgO has a lower melting point than the alkalis it replaces, it can be used to refractoryize glazed stoneware at very low temperatures.
Frits Are Another Great Candidate for MgO Strategy
One of the most common types of glaze is a frit, which is a mixture of raw materials melted and then quenched and ground into a powder. Frits can be made from feldspar, talc, dolomite, and soda, but MgO is the only fluxing oxide that can produce a crazing-resistant matte without affecting surface character.
Increasing MgO Content to Refractoryize Tiles
MgO can be used in refractory ceramics to stabilize clays and other refractory metals in tile. MgO is inert to most metals and slags, is highly resistant to heat, and has excellent oxidation stability. It is widely used in the manufacturing of refractory brick and is an essential ingredient in many refractory masonry products, such as sandstone and limestone.
