The Main Synthesis Method of Titanium Carbide |
What is titanium carbonide?
TiC is a cubic, light-gray, chemically insoluble crystal system.
TiC is an iron-gray crystal that has metallic luster. It's a cubic-shaped crystal of NaCl type. The lattice constant for this structure is 0.4329nm. Fm3m stands for space group. Carbon atoms, and titanium Atoms between TiC can be considered strong covalent bond in the lattice. The bonded atoms are similar to metals in that they have a high melting, boiling, and hardness. TiC can be used to make cermets as well heat-resistant alloys, cemented carides, anti-wear and radiation materials.
The Synthesis Method for Titan Carbide
Carbon black and titanium dioxide are two of the raw materials.
After the mixture of high-purity titanium dioxide with carbon black is complete, it's press-formed using a horizontal or vertical carbon tube furnace in hydrogen. The titanium carbide powder is obtained by pulverizing the titanium carbide at a temperature of 19002300degC. Sponge titanium, or titanium alloy, and titanium waste, as well as carbon black can be used to produce raw materials. Carbon black and sponge titanium are mixed together in the right proportions and then heated in high-purity hydrogen stream until they reach 15001700degC. Titanium carbide.
The direct carbonization of titanium steel:
It is reduced by sodium, or made from titanium hydride. Less than 325 mesh was mixed with carbon black. After that it was molded in a container of graphite and heated to 15001700degC under high-purity hydrogen. The type of raw material and the particle size, along with their reactions performance, will affect the reaction temperature and hold time.
Gas phase reaction method:
Hydrocarbons containing hydrogen (methane-, benzene etc.) are mixed into the steam of titanium Tetrachloride. The mixture is then used to prepare the titanium carbide by either induction heating, or using other methods. Reaction results in the formation of titanium carbide on substrate. Reaction conditions like the reaction temperature, gas flow rate, concentration, and reaction time are all different. The form of precipitated titan carbide also differs.
