Titanium carbide and Titanium carbide ceramics
Review of titanium carbide
Titanium carbide (chemical formula TiC), molecular weight: 59.89 Grey metal cubic lattice-solids with gray metal faces. Melting point 3140+ 90, boiling point 48220, relative density 4.93 A hardness greater than 9 Water is insoluble, but it can be soluble with nitric acid or aqua regia. It can be stable at 800C, but it will erode in air higher than 2000C. At 1150C, it can react to pure O2.
A metal luster that is made of titanium carbide and iron-gray crystalline is an alloy of the metals. This metal has similar characteristics to other metals, such as high melting points, boiling points and hardness. Also, it is very thermally and electrically conductive. At very low temperatures, superconductivity will be also displayed. This material is commonly used for the production of cermet, hard alloy, heat-resistant, anti-wear, and radiation materials.
Material made from titanium carbide-base ceramic material
As a transition metal carbide, titanium carbide clays cannot be used for engineering purposes. Instead, composite materials are often used as a reinforcement phase. However, there is more to the material than can be applied, like the development of titanium carbide pottery.
Ceramic is Titanium Carbide Fund. This ceramic can be made from a type of alloy or metal TiC ceramic phase heterogeneous ceramic material. Both ceramics have high strength, hardness and wear resistance. They also possess chemical stability and mental toughness.
The most common transition metal carbides are titanium carbide ceramics. TiC is unique because it has a combination of metallic, covalent, and ionic bonding in one crystal structure. TiC has basic properties such as high hardness (high melting point), wear resistance, electrical conductivity and durability.
The properties of titanium carbide
TiC, which is light metallic gray in theory, contains 20.05% carbon. Chemically, it is stable and nearly inert against hydrochloric acid and sulfuric acid. TiC dissolves easily in many oxidizing chemicals such as aqua regia or nitric acid. Also, it is soluble in melts of alkaline oxygen. Nitrogen forms at temperatures above 1500°C when heated in a nitrogenous environment. TiC can be corroded with chlorine gas at very high temperatures. It also oxidizes quickly in the atmosphere.
TiC's density is 4.94g/cm3. It has the Mohs Hardness of 9+, microhardness at 3200kg/mm2 and elastic modulus of 309 706 MPa. The material's fracture modulus at 3000 2600 is 499.8 and 843.2 MPa when heated to room temperature. The temperature modulus for fracture is 107.78 mph to 111.6mpa at 982 and 54.4 to 63.92mpa 2200. The melting temperature of TiC is 3160 degrees C and the resistivity at room temperatures is 180 250 This conductor can also be used at higher temperatures. It has a thermal expansion coefficient of 4.12 x 10-6/degF between room temperature (593degC) and 593degC (593degC). Thermal conductivity is 0.01 CAL /cm /degC.
Titan carbide ceramics are used
1. Material with multiple phases
The titanium carbide ceramics can be used to make superhard tools. These ceramics consist of TiN and WC as well as Al2O3 or other raw materials. This material has a high melting temperature, hardness, chemical stability and is the most preferred material for cutting tool-resistant parts. High-speed wire conductors and carbon steel can be cut using titanium carbide ceramic. This is due to its high oxidation resistance as well as no crescent wear. A variety of multiphase ceramic tools made with titanium carbide can be found.
2. Materials for Coating
As a protective coating for the diamond's surface, titanium carbide provides a wear-resistant finish. Some powerful carbides are applied to the diamond surface by chemical and physical processes in order form metals or other alloys. The metals or alloys are formed when they react at high temperatures with carbon atoms. These carbides are able to bond well to diamonds and can also be permeated with matrix metal. It enhances diamond-matrix metal adhesion. The tool's life span can be prolonged by depositing titanium carbonide films.
3. Research into the nuclear fusion reaction
The titanium carbide and the (TiN+TiC) composite coated material produce a tritium-resistant layer of permeability on the surface. It can resist heat radiation and resist high temperature gradients and thermal cycle.
Titanium carbide can be used to make smelting Tin, Lead, Cadmium and Zin, as well as other metal crucibles.
