Titanium diboride target is made of titanium diboride. Titanium diboride is a gray or grayish black substance with a hexagonal (AlB2) crystal structure, a melting point of up to 2980 ° C, a density of 4.52g/cm³, and a microhardness of 34Gpa, so it has extremely high hardness. It has an oxidation resistance temperature of up to 1000℃ in the air, and remains stable in HCl and HF acids, showing excellent acid corrosion resistance. The material properties are as follows: coefficient of thermal expansion: 8.1×10-6m/m·k; Thermal conductivity: 25J/m·s·k; Resistivity: 14.4μΩ·cm;
This material also has good thermal and electrical conductivity, so it is widely used in various industrial fields, such as vacuum coating, ceramic cutting tools and molds, high temperature crucible, engine parts and so on. At the same time, the titanium diboride target is also an important target for the preparation of titanium alloys, high hardness ceramics and concrete reinforcement.
How to Produce the titanium diboride target？
1.Direct synthesis method: This method is to directly combine titanium and boron powder in a high-temperature reactor to produce titanium diboride. However, the reaction temperature of this method needs to be above 2000℃, the raw material price is high, the process is not easy to control, the reaction is incomplete, the generated TiB2 is low in purity, and it is easy to produce TiB, Ti2B and other compounds.
2.Borothermal method: This method uses TiO2 (purity higher than 99%, the structure of ase, particle size 0.2-0.3μm) and amorphous B (purity 92%, particle size 0.2-0.3μm) as raw materials, through a specific ratio and ball milling process (usually done under vacuum), at a reaction temperature of no more than 1100 ° C to prepare titanium diboride.
3.Melt electrolysis: In this method, titanium oxides react with alkali (or alkaline earth) metal borates and fluorates under the conditions of melt electrolysis to form titanium diboride.
Each of these production processes has its own characteristics, the specific choice of which process depends on production demand, equipment conditions and economic costs and other factors.

How much the titanium diboride target?
The price of titanium diboride targets varies depending on the brand, purity, size, particle size, packaging specifications and other factors. According to the quotation of some suppliers, the price can range from tens to thousands of yuan. For example, the price of some titanium diboride targets is 85 yuan, 10 yuan (experimental scientific research), 285 yuan (granular) 2000 yuan targets or higher (high purity, magnetron sputtering). It should be noted that these prices are only reference values, the actual price may change due to market supply and demand, raw material price fluctuations and other factors.
How to Choose the high quality of the titanium diboride target?
1.Appearance and color: Titanium diboride targets are usually gray or gray-black, and the appearance should be uniform without obvious impurities or color spots. If the color is too dark or light, or there are impurities on the surface, it may indicate that its purity is not high or there is a problem in the preparation process.
2.Purity: Purity is an important index to measure the quality of titanium diboride target. The higher the purity, the more stable its performance and the less impurity content. The purity of the target can be tested by chemical analysis and other methods to ensure that it meets the requirements of use.
3.Density and hardness: Titanium diboride has a high density and hardness, which is also an important embodiment of its excellent performance. By measuring the density and hardness of the target material, its quality can be preliminarily judged. If the density and hardness do not meet the standards, it may indicate that there is a problem with the preparation process or the raw material.
4.Electrical and thermal conductivity: Titanium diboride has good electrical and thermal conductivity, which is an important reason for its wide application in the field of electronics and energy. The electrical and thermal conductivity of the target can be evaluated by measuring the resistivity and thermal conductivity of the target.
5.Chemical composition analysis: Through chemical composition analysis, the content and proportion of various elements in the target can be understood, so as to determine whether it meets the standard. If the content of impurity elements in the target is too high, or the proportion of main elements does not meet the requirements, it may indicate that its quality is poor.
Preparation process: Understanding the preparation process of the target can also help judge its quality. If the preparation process is advanced and the control is strict, the target material with better quality can usually be obtained. On the contrary, if the preparation process is backward or poorly controlled, the quality of the target may be unstable or defective.
6.Supplier reputation: Choosing a reputable supplier is also an important part of ensuring the quality of the target material. You can check the supplier’s qualification, performance and customer reviews and other information to understand its reputation and product quality level.
