Zhengzhou DEERXIN Tungsten & Molybdenum Technology Co., Ltd.
Molybdenum disilicide powder is an inorganic compound with the chemical formula MoSi. 2 Its molecular weight is approximately 152.11 (some data indicate 152.12, with slight variations due to differences in computational precision). It appears as a black or gray powder with high purity, typically exceeding 99.9%. Its crystal structure is tetragonal, its density is about 6.26 g/cm³, and its melting point reaches as high as 2030℃.
Molybdenum disilicide powder exhibits dual characteristics of both metals and ceramics. At room temperature, it is chemically stable and does not react with most acids or bases; however, it can dissolve in a mixed acid consisting of nitric acid and hydrofluoric acid. It possesses excellent high-temperature oxidation resistance, forming a silica glass film at elevated temperatures that effectively inhibits further oxidation, thereby enhancing its antioxidant performance. In addition, molybdenum disilicide powder is a good conductor with low electrical resistivity, making it suitable for manufacturing electric heating elements, thermocouple protective sheaths, and other similar applications.
Due to its excellent physical and chemical properties, molybdenum disilicide powder is widely used in fields such as high-temperature oxidation-resistant coating materials, electric heating elements, integrated circuits, and structural materials. It plays an important role in the energy chemistry industry, microelectronics industry, aerospace industry, and automotive industry.
