SPK Customized MoSi2 heating element MoSi2 resistive heating element is a high temperature resistant and anti-oxidation resistance heating element based on molybdenum disilicide. When used in high-temperature oxidizing atmosphere, a layer of bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon molybdenum rod from oxidation, so the silicon molybdenum rod element has unique high-temperature oxidation resistance. Under oxidation atmosphere and the maximum service temperature is 1800 �¢??, the resistance of the silicon molybdenum rod electric heating element increases rapidly with the increase of temperature, and the resistance value is stable when the temperature is constant. Under normal conditions, the element resistance does not change with the length of service time, so the new and old silicon molybdenum rod heating elements can be mixed.

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc. In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%. Metal silicon particles: 1-200mm silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes. (1) Production of silicone rubber, silicone resin, silicone oil and other silicone. (2) Manufacture high-purity semiconductors. (3) Prepare alloy.
