What is titanium diboride? Titanium diboride It is a gray or gray-black powder with a hexagonal crystal structure. The melting point is 2900 ℃. The hardness (HV) is 34GPaI, and the density is 4.52. It is wear-resistant, acid and alkali resistant, has strong thermal conductivity, and has a small coefficient of thermal expansion. It has excellent chemical stability and thermal resistance. The oxidation resistance temperature of titanium diboride in the air can reach 1000 ℃. The stable titanium diboride (TiB2) in HC1 and HF acid is the most stable compound of boron and titanium, a C32 type of structure that combines with its valence bond; the structural parameters of the complete crystal of the quasi-metallic compound belonging to the hexagonal system are. A is 0.3028 nm, and C is 0.3228 nm. The boron and titanium atomic planes in the crystal structure alternately appear to form a two-dimensional network structure. Covalent bonds combine B and the other three B, and the remaining electron forms a large π bond. This kind of graphite-like layered structure of boron atoms and the outer electrons of Ti determines that TiB2 has good conductivity and metallic luster. The Ti-B bond between boron and titanium atoms determines this material's high hardness and brittleness.
Characteristics of titanium diboride as structural material and functional material respectively 1. In terms of structural materials. The high strength and hardness of titanium borate make it possible to make tools, wire drawing films, sandblasting nozzles, and hard tool materials. At the same time, it can also become an additive of composite materials 2. In terms of functional materials, the resistivity of titanium borate is very similar to that of pure iron, so its application in functional materials is very promising. Through the electrical properties of titanium borate, flexible PTC materials can be made.
Preparation of titanium diboride Mechanochemical reaction method (MR): This method is to place the reactant powder in a high-energy ball mill, and the powder will undergo repeated changes from deformation to fragmentation under the action of the extrusion and shearing of the grinding ball. The violent friction and collision of the ball milling medium will cause the mechanical energy to be converted into chemical energy, thus synthesizing the required reactants. Compared with the previous two methods to prepare titanium diboride, the mechanochemical reaction method has a lower synthesis temperature, a Wide source of raw materials, and low cost.
Price of titanium diboride Titanium diboride particle size and purity will affect the product's price, and the purchase volume can also affect the cost of titanium diboride. A large amount of large amount will be lower. The price of titanium diboride can be found on our company's official website.
