What is titanium carbide? Titanium carbide is a gray-white metallic powder belonging to a sodium chloride-type cubic crystal system, with a relative density of 4 93. Lattice constant a=0. 4329, melting point 3140 ℃, boiling point 4820 ℃, high hardness, Mohs hardness 9~10, microhardness 3000kg/mmz, elastic modulus 2940N/mm2, bending strength 240~400N/nn2, thermal expansion coefficient 7 seventy-four × 10-6/K, thermal conductivity 21W/(m.K), heat generation - 183 4kj/mol. insoluble in water, soluble in nitric acid. It does not react with hydrochloric acid and can be made by heating bone charcoal and titanium dioxide in an electric furnace. It is an important component of cemented carbide.
Use of titanium carbide 1. Used as an additive for cutting tool material and melting crucible for bismuth, zinc, and cadmium, preparing semiconductor wear-resistant film, and HDD large-capacity memory device 2. It is an important component of cemented carbide and is used as a deoxidizer in the steel-making industry 3. As a cermet, it has the characteristics of high hardness, corrosion resistance, and good thermal stability.
Preparation of titanium carbide High-temperature self-propagating synthesis (SHS): SHS is derived from the exothermic reaction. When heated to a proper temperature, fine Ti powder has high reactivity. Therefore, once the combustion wave generated after ignition passes through the reactants Ti and C, Ti and C will have enough reaction heat to generate TiC. SHS reaction is very fast, usually less than one second. This synthesis method requires high-purity, fine Ti powder as raw material, and the output is limited. Reactive ball milling technology method: Reactive ball milling technology is a technology that uses the chemical reaction between metal or alloy powder and other simple substances or compounds in the process of ball milling to prepare required materials. The main equipment for preparing nanomaterials using reactive ball milling technology is the high-energy ball mill, mainly used to produce nanocrystalline materials. The reactive ball milling mechanism can be divided into two categories: a mechanically induced self-propagating high-temperature synthesis (SHS) reaction. The other is reaction ball milling without obvious exothermic, and its reaction process is slow.
