Product detail
Silicon nitride (Si3N4) ceramic is an inorganic material ceramic that does not shrink during sintering. It possesses high strength, low density, and high-temperature resistance. Additionally, silicon nitride ceramic has strong corrosion resistance, reacting only with hydrofluoric acid and not with other inorganic acids. Si3N4 also exhibits excellent thermal shock resistance, remaining intact even when heated to 1000°C in air and then rapidly cooled. Therefore, silicon nitride ceramic thermocouple protection tubes, made from silicon nitride ceramic, have exceptional corrosion resistance and high-temperature strength, making them a top choice for applications involving aluminum and molten metal handling.
In terms of temperature control in aluminum foundries and smelters, Silicon nitride thermocouple protection sheaths offer outstanding performance by providing consistent temperature monitoring of the melt, thereby improving the quality of the finished castings. In addition to their excellent physical properties, Silicon Nitride thermocouple protection sheaths are non-wetting to most non-ferrous alloys, allowing them to resist slag buildup, resulting in very low maintenance costs. Compared to competing materials like cast iron, silicon carbide, and alumina, Si3N4 Thermocouple Protection Tube are highly cost-effective.
