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

ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting and other casting industries.
As a new type of refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen additive in the steelmaking industry.
Silicon nitride material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a certain amount of nitrogen for molten steel.
Deoxidizer: Ferro silicon is used in the steelmaking industry as a precipitation deoxidizer and diffusion deoxidizer.
Reducing agent: high-silicon ferro silicon or siliceous alloys can be used as reducing agents for the production of low-carbon iron alloys in the ferroalloy industry.
Alloying agent: Ferro silicon can be used as alloying agent for low-alloy structural steel, composite steel, spring steel, bearing steel, heat-resistant steel and electric silicon steel smelting, to produce single crystal silicon or to prepare non-ferrous metal alloys.
Inoculant: adding ferro silicon to cast iron can be used as an inoculant for nodular cast iron to prevent the formation of
carbides, promote precipitation and spheroidization of graphite, thereby improving the properties of cast iron.
Coating: Ferro silicon powder can be used as a suspension phase in the beneficiation industry, and can be used as a coating for welding rods in the welding rod manufacturing industry.
