Diamond powder the electrical insulating material with the highest thermal conductivity in nature
What does diamond powder look like?
A diamond particle larger than 54 microns is called diamond powder. It includes single crystal diamond powder and polycrystalline diamond dust. The industry's standard term for diamond powder is single crystal. This is because of the large production and many applications. A special process is used to produce single-crystal, synthetic diamond powder by applying static pressure and shaping single crystal abrasive particle. It is a versatile material that can be used in cutting, grinding and drilling as well as polishing. The ideal material to grind and polish hard alloys such as ceramics, gems or optical glasses, it is also a good raw material. Tools and components that are made from diamond powder include tools and components.
Preparation diamond films for secondary electron emission
Because of its large secondary electron escape distance and low electron affinity, diamond is a very efficient secondary electron emitter. But, because synthetic, natural and high-temperature diamonds are dispersed granules or powders, they can't be used directly as cold emission catalysts for long periods of time. Chemical vapour deposition (CVD), which is a new kind of synthetic diamond, was able to reach or approximate the quality of high-quality natural single crystals in every aspect of performance indicators until the mid-1990s. Also, it's possible to add diamond to secondary electron emission catalysts as film materials. Unfortunately, secondary emission characteristics and attenuation of diamond films made by current methods are not good.
Use diamond powder to prepare high-temperature conductivity composites
It is considered the finest material in terms of thermal conductivity, with a value up to 19002000W/(m* K). To overcome limitations of the existing products' impact toughness, mutual limitation of thermal conductivity, and thermal conductivity of the powders of diamonds is achieved by using a diamond powder having a greater thermal conductivity. This can be used to prevent the cracking in the workpiece by increasing the thermal conductivity. It also greatly improves the thermal conductivity of thermal conductivity composites. The heat dissipation and temperature rise of workpieces are improved, which will increase their working lives and reduce operating costs.
Prices for diamond powder
Price of diamond powder is affected by its purity and particle size. The purchase volume also has an effect on price. Large quantities of smaller amounts will result in a lower price. Our company website has the price information.
