Description

Silicon nitride possess a unique combination of physical properties, such as high strength, toughness, excellent thermal shock resistance and resistance to corrosion, which make it the perfect material in this application. Silicon nitride thermocouple protection sheaths are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are extremely cost effective compared to other materials, such as cast iron, silicon carbide and alumina. Manufacturing technique: Iso-static pressing Characteristics: non-wetting property Low coefficient of thermal expansion Moderately high elastic modulus Excellent thermal shock resistance Ability to withstand high structural loads to high temperature Applications: Advanced ceramic thermocouple protection tubes or sheaths for use in the molten aluminium and non-ferrous industry.。 Thermocouple protection sheaths are used extensively for continuous temperature measurement in nonferrous metals.
