Sialon
McDanel Advanced Ceramic Technologies LLC
SiAlON ST is an alloy of silicon nitride and aluminum oxide. This
superior refractory material has the combined properties of silicon
nitride (high strength, hardness, fracture toughness and low thermal
expansion) and aluminum oxide (corrosion resistance, refractoriness
and oxidation resistance). Traditional refractory products can be
used only in high temperature applications where one or two of the
following properties are required: thermal shock resistance, mechanical
strength, corrosion resistance, abrasion resistance or electrical
insulation. McDanel Advanced Ceramic Technologies LLC SiAlON ST combines high levels of these properties
in one refractory material.
SiAlON
ST is uniquely qualified for non-ferrous molten metal applications
and high wear or high stress environments up to 1250°C. SiAlON
ST is non-wetting for most non-ferrous metals. It is gas-tight,
chemically inert, resistant to corrosion and features high strength,
hardness and thermal shock resistance.

SiAlON ST |
Good for molten metal applications, high wear or high impact
environments up to 1250°C. It is non-wetting for most nonferrous
metals, gas tight, chemically inert, resistant to corrosion
and metal attack and features high strength hardness and thermal
shock resistance. |

SiAlON BN |
Good for molten steel applications up to 1500°C. It is
a composite material combining SiAlON ST with increased thermal
shock resistance and lubricity of Boron Nitride. It compromises
porosity, hardness and strength to achieve higher temperatures
and corrosion resistance. |
