What is diamond powder? Diamond powder is that diamond particles greater than 54 microns, including single crystal and polycrystalline diamond powder. Because the output of single crystal diamond powder and wide application fields is large, diamond powder is usually called single crystal diamond powder in the industry. Single -crystal diamond powder is produced by using a special super material process through static pressure and shaping the synthetic diamond single crystal abrasive particles. Diamond powder has high hardness and good abrasion resistance, which can be widely used for cutting, grinding, drilling, polishing, etc. It is the ideal raw material of grinding and polishing hard alloys, ceramics, gems, optical glass and other high hardness. Diamond powder products are tools and components made of diamond powder.
Preparation of diamond films for secondary electron emission As a wide band gap material, diamond has very good secondary electron emission performance due to its low electron affinity and large secondary electron escape depth. However, since natural, high-temperature, and high-pressure synthetic diamonds are dispersed powders or granules, they cannot be directly used as cold emission cathodes for a long time. Until the mid-1990s, the chemical vapour deposition (CVD) diamond film, a new type of synthetic diamond material, could reach or approach the level of natural, high-quality single crystals in all aspects of performance indicators, and it is possible to apply diamond in the form of film materials to secondary electron emission cathodes. However, the secondary emission coefficient and attenuation characteristics of diamond films prepared by existing methods for secondary electron emission are poor.
Preparation of high thermal conductivity composites using diamond powder The thermal conductivity of diamond powder is up to 1900~2000W/(m · K), which is the best material. The diamond powder with higher thermal conductivity is applied to manufacture thermal conductivity composites, and the diamond powder is used to prepare high thermal conductivity composites to overcome the shortcomings of mutual restriction of thermal conductivity and impact toughness of existing products. Thus, it can effectively prevent the cracking of the workpiece under the premise of improving the thermal conductivity, greatly improving the thermal conductivity of the thermal conductivity composite, improving the heat dissipation of the workpiece, and reducing the temperature rise of the workpiece, thus improving the working life of the workpiece and reducing the operating cost.
Price of diamond powder Diamond powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of diamond powder. A large amount of large amount will be lower. The price of diamond powder can be found on our company's official website.
