INNOVACERA manufacture a range of silicon nitride and advanced ceramic thermocouple protection sheaths for use in the aluminium and molten metal handling industries. They are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are extremely cost effective compared to competitive materials, such as cast iron, silicon carbide and alumina.
INNOVACERA 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 stand out material in this application.
Silicon nitride protection tubes are world renowned for their outstanding performance in contact with non-ferrous molten metals, particularly aluminium and its alloys and zinc. They allow constant temperature monitoring of the melt resulting in improved quality of the finished casting. In addition to its excellent physical properties, it is also non-wetting to most non-ferrous alloys, making it resistant to build up of dross and is therefore very low maintenance.
For high temperature applications above 1200°C, silicon nitride ceramic protection tubes is the preferred choice.
