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.
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 sheaths or tubes for use in the molten aluminium and non-ferrous industry.。
Thermocouple protection sheaths are used extensively for continuous temperature measurement in nonferrous metals.
