Alumina Ceramic Products

Alumina


Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments.  McDanel offers Alumina in various purity levels, including 99.8% and 99.0%.  The level of purity, grain size, and density required is dependent on the rigors of the application and the component configuration.

Mullite Ceramic Products

Mullite


Mullite (3Al2O3 2SiO2) is a refractory oxide material combining low thermal expansion, good mechanical strength, and resilience at elevated temperatures.  McDanel Mullite is formulated to produce dense, impervious shapes, with optimized thermal shock resistance and strength.

Zirconia Ceramic Products

Zirconia


Zirconia (ZrO2) is an extremely refractory material.  It possesses excellent chemical inertness and corrosion resistance at temperatures well above the melting point of alumina.  McDanel Zirconia is fully stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during thermal cycling.  In addition to its high temperature capability, Zirconia offers low thermal conductivity and is electrically conductive above 800°C.  Also has the unique ability to allow oxygen ions to move freely through the crystal structure above 600°C.

Sialon Ceramic Products

Sialon


McDanel Sialon is a ceramic alloy which is iso-structural with beta silicon nitride and contains aluminum and oxygen in solid solution.  Consequently, it exhibits a very desirable combination of the properties of both silicon nitride (high strength, hardness, fracture toughness, and thermal shock resistance) and alumina (refractoriness, corrosion resistance, and oxidation resistance).

 

Traditional refractory products are used in high temperature applications where one or two of the following requirements are satisfied: corrosion resistance, thermal shock resistance, mechanical strength, abrasion resistance, electrical insulation.  McDanel Sialon combines high levels of each of these properties in a single material.
