White Fused Alumina

  • AL

    AL is a white aluminum oxide obtained from the fusion of calcined alumina in electric arc furnaces. It is recommended for ceramic applications where purity, chemical stability or high refractoriness is an issue to be considered.

Fused Mullite

  • MUB

    MUB is a fused mullite obtained from fusion of high purity sand and alumina in an electric arc furnace. It presents low thermal expansion and high thermal shock resistance that make MUB an excellent material for investment casting and other refractory applications.

  • MUBS

    MUBS is a fused mullite obtained from fusion of silica sand and alumina in an electric arc furnace. It is less pure than MUB but also presents low thermal expansion and high thermal shock resistance that make MUBS an excellent material for investment casting and other refractory applications.

  • MUBW

    MUBW is an extremely pure fused mullite obtained from fusion of silica sand and alumina in an electric arc furnace. It presents low iron contamination, low thermal expansion, high thermal shock resistance and high temperature strength. It is an excellent material for investment casting and other refractory applications.

Calcined Alumina

  • ACW

    ACW is a high purity calcined aluminum oxide powder that is ideal for a wide variety of applications including advanced technical ceramics, surface finishing, compounds, lapping, polishing, and more.

Silicon Carbide

  • ELECTROCARB┬« Black Silicon Carbide

    Ideal for a wide variety of applications including metal-matrix composites, kiln furniture, bonded and specialty refractories and many more.

  • Green Silicon Carbide

    Ideal for many applications including wear resistant seals/rings/nozzles, coatings, metal-matrix composites, kiln furniture, silicon carbide heating elements, body & vehicle armor, and many more.

  • Green Silicon Carbide (0.7 Micron)

    Green Silicon Carbide milled to an average particle size of 0.7 microns and has a specific surface area of more than 12 m2/g. Ideal for wear resistant ceramics (rings, seals, nozzles), ceramic armor, and more.

Baron Carbide

  • Boron Carbide

    With its strength to weight ratio and low thermal conductivity, Boron Carbide is ideal for a wide variety of applications including blasting nozzles, body armor, ceramic & metal-matrix composites, aerospace applications, refractory anti-oxidant, lapping, honing stones, nuclear technology, ultrasonic machining, and many others.

  • Boron Carbide (0.7 Micron)

    Our Boron Carbide 0.7 Micron, is ideal for a wide variety of applications including wear resistant ceramics such as rings, seals, bearings and blasting nozzles, as well as body armor, composites, aerospace applications, and more.
