What is hafnium disilicide? Hafnium disilicide is a kind of transition metal silicide. It has the characteristics of a high melting point, high hardness, high wear resistance, and oxidation resistance. It is used as ceramic material, and various high-temperature resistant components and functional components Hafnium disilicide nanomaterials exhibit special electrical and optical properties and have potential applications in optoelectronics.
Preparation of hafnium disilicide The main methods of hafnium disilicide are the direct synthesis of sponge hafnium and the resynthesis of metal silicon generated by carbon reduction of hafnium dioxide. The direct synthesis of sponge hafnium is the direct synthesis of sponge hafnium and silicon. The cost of sponge hafnium is high, and the re fusibility of silicon and hafnium is poor. Silicon in liquid has poor mobility and cannot be fully combined with silicon. The degree of alloying is not high, and there is simple silicon. The method of synthesizing metal silicon by reducing hafnium dioxide with carbon is to reduce hafnium dioxide with simple carbon to produce metal hafnium. During the reduction process, to fully reduce hafnium dioxide, only excessive carbon can be used so that there is free carbon in metal hafnium. Silicon carbide impurities will be produced in the subsequent steps and the silicification process; If the amount of carbon is insufficient, there will be a small amount of hafnium oxide that has not been reduced. After silicification, there will be hafnium oxide, which affects the purity of the product and cannot meet the high purity standard.
Application of hafnium disilicide Hafnium disilicide is a kind of transition metal silicide, which is a kind of refractory intermetallic compound. Due to its unique physical and chemical properties, it has been successfully applied to the fields of complementary metal oxide semiconductor devices, film coatings, block structure components, electric heating elements, thermoelectric materials, and photovoltaic materials Its nanomaterials show special electrical, optical, magnetic and thermoelectric properties, and even have potential applications in the field of catalysis. However, traditional preparation methods such as metallurgy or physical methods cannot meet the preparation requirements of transition metal silicide nanomaterials. Therefore, it is very important to find a simple, controllable, and universally applicable preparation method for the wide application of transition metal silicide nanomaterials.
The price of hafnium disilicide Hafnium disilicide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of hafnium disilicide. A large amount of large amount will be lower. The price of hafnium disilicide can be found on our company's official website.
