Stamford CT, USA — ??OMEGATITE?? 650 is the ceramic sheath which 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, chemically inert, high temperature capabilities and oxidation??resistance).
Not recommended for caustic solutions and hydrofluoric acid.
Most refractory products can be used only in high temperature applications where one or two of the following properties are required: thermal shock resistant, mechanical strength, corrosion??resistance, abrasion resistance or electrical insulation.
OMEGATITE?? 650 combines all these properties in one refractory material. Preheating of the process is not necessary. ??It??is uniquely qualified for non-ferrous molten metal applications and high wear or high impact environments up to 1250 ??C (2282 ??F).
OMEGATITE?? 650 thermocouple sheaths are used extensively for continuous measurements in nonferrous metals. In molten aluminum, OMEGATITE?? 650 is thermally shock resistant, nonwetting, does not contaminate the melt, provides continuous, reliable temperature measurement, and is resistant to degradation even in aggressive aluminum lithium alloys.
