What is Zirconium Silicide? Zirconium Silicide, as a zirconium silicon intermetallic compound, is a kind of high-temperature ceramic material with high hardness, high melting point, high conductivity, high thermal conductivity, and excellent thermal shock resistance. Given these superior physical and chemical properties of zirconium silicon intermetallic compound, it is a structural or new engineering material that can be applied to high-temperature corrosive media Properties Zirconium silicide is a gray rhombic luster crystal of steel, with a relative density of 4.8822. Zirconium silicide is insoluble in water, inorganic acid, and aqua regia but soluble in hydrofluoric acid. Preparation method Zirconium silicide can be obtained by reacting a mixture of zirconium powder and silicon powder in a certain amount at high temperatures in isolated air.
Synthetic methods of Zirconium Silicide Synthesis method A method for preparing zirconium silicide nanomaterials, which includes the following steps: (1) add 5mmol of zirconium dioxide, 5mmol of silicon powder, and 50mmol of lithium metal into a 20ml stainless steel autoclave and seal it, then put the autoclave into an electric furnace capable of temperature programming, set the temperature rise rate of the electric furnace to 10 ℃ per minute, raise the temperature of the electric furnace to 600 ℃, maintain the reaction for 40 hours after the temperature rise is completed, and then cool down from the Chemicalbook to room temperature after the reaction, Then open the autoclave to take out the product (black sediment); (2) The reaction products are first washed with distilled water, then washed with dilute hydrochloric acid and anhydrous ethanol respectively, filtered the washed products, and then dried in a vacuum drying oven at 60 ℃ for 4 hours to obtain zirconium silicide nanomaterials. According to the quality of the prepared zirconium silicide nanomaterials and the quality of the raw material zirconia used, the yield of zirconium silicide is 85%.
Use of Zirconium Silicide As a fine ceramic raw material powder, it produces crucibles, carbon ceramic brake pads, and brake discs for semiconductor film production. The mass fraction of Zirconium Silicide is 10~15%. Adding this mass fraction of Zirconium Silicide to ceramic matrix composites can significantly reduce the sintering temperature of material preparation. Research on the elasticity and anisotropy of zirconium silicide. The compounds generated by metal and silicon are metal silicides, which are divided into two categories: 1. Refractory metal silicides, refer to silicides of IVB, VB, and VIB elements in the periodic table, such as titanium silicide, zirconium silicide, tantalum silicide, tungsten silicide, etc., two silicides of precious metals and near precious metals, silicide targets, platinum silicide, cobalt silicide, etc. In a word, metal silicides are relatively hard substances with a metallic luster, high conductivity, positive resistance humidity coefficient, and magnetism in most cases. Silicides of refractory metals have a high melting point, hardness and compression strength, High-temperature creep strength, medium density, tensile strength, and good thermal and mechanical properties. The reaction between metal and silicon reduces metal activity, so silicide's chemical stability is quite good.
Price of Zirconium Silicide Zirconium Silicide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Zirconium Silicide. A large amount of large amount will be lower. The price of Zirconium Silicide can be found on our company's official website.
