Zirconium disilicide is a kind of new engineering material which can be applied to high temperature corrosive medium

Overview of Zirconium disilicide ZrSi2 powder

Zirconium disilicide is an inorganic compound, chemical formula ZrSi2, composed of Zirconium and silicon atoms. Zirconium disilicide belongs to silicides and is a kind of gray square crystalline powder. Zirconium disilicide is a lustrous steel-gray rhombic crystal with a relative density of 4.8822. Zirconium disilicide is insoluble in water, inorganic acids, aqua regia and hydrofluoric acid. Method: the proportion of zirconium powder and silicon powder mixture in isolation under the high-temperature reaction and obtained.

Zirconium disilicide as Zirconium - silicon intermetallic compound, is a kind of high hardness, high melting point, high conductivity, high heat conductivity, good thermal shock resistance of high-temperature ceramic material, given the silicon Zirconium - intermetallic compound has the superior physical and chemical properties, is a kind of can be applied to high-temperature structure material of corrosive medium or new engineering materials.

Zirconium disilicide main irritating effects: may cause inflammation on the skin; May cause irritation above the eyes; Sensitization: No known sensitization.

A method for preparing Zirconium disilicide nanomaterials includes the following steps:

Will be 5 tendencies for zirconium dioxide, 5 tendency for silicon powder and 50 tendencies for lithium metal joining into 20 ml stainless steel autoclave and closed, then can the autoclave in the electric furnace, the temperature-programmed set electric heating rate per minute is 10 ℃, the furnace temperature to 600 ℃, temperature maintain reaction 40 hours, after the completion of reaction after natural cooling to room temperature, and then open the autoclave to take out the product (black sediments); The reaction products were washed with distilled water, then respectively with dilute hydrochloric acid and anhydrous ethanol washing time, after washing the product of filtering, then 60 ℃ in the vacuum drying oven drying 4 hours for Zirconium disilicide nanomaterials, based on the preparation of Zirconium disilicide nanometer material quality and the quality of the raw material of Zirconium dioxide used, it is concluded that Zirconium disilicide yield of 85%.

Application of Zirconium disilicide ZrSi2 powder

Zirconium disilicide is commonly used as fine ceramic powder and crucible for the production of semiconductor thin film.

There is also a high-density ceramic matrix composite: Zirconium disilicide- Zirconium disilicide- tungsten carbide ceramic matrix composites. The material is made from Zirconium disilicide powder, Zirconium disilicide and tungsten carbide (purity >98.0%), prepared by a two-step hot pressing sintering process. Among them, the mass fraction of zirconium diboride powder is 75~90%. Adding higher content of zirconium diboride into ceramic matrix composites is beneficial to improve the physical and chemical properties of composites. The mass fraction of zirconium disilicide is 10~15%, adding this mass fraction of zirconium disilicide into ceramic matrix composites can significantly reduce the sintering temperature of material preparation. The mass fraction of WC is 0~10%. The addition of WC can promote the growth of grain anisotropy inside the material. The grain size of the three original powders is 1 to 5 microns, which is conducive to the uniform mixing of all phases. This material can be used as a surface insulation layer for hypersonic aircrafta and has the characteristics of high density and high mechanical properties.
