藁城What advantages does diamond micro-powder have in the field of new materials?

Diamond micro-powder has significant advantages in the field of new materials, mainly reflected in the following aspects:

1. Hardness and wear resistance:

Diamond micro-powder features extremely high hardness and wear resistance, with a Mohs hardness of 10 and a microhardness of 10,000 kg/mm², which is 1,000 times higher than that of quartz and 150 times higher than that of corundum. This makes diamond micro-powder an ideal raw material for grinding and polishing hard alloys, ceramics, gemstones, optical glass and other high-hardness materials.

2. High thermal conductivity:

Diamond micro-powder has an outstanding thermal conductivity, which is much higher than that of traditional metals such as copper and aluminum. This characteristic gives diamond micro-powder a significant advantage in the field of thermal management. It can be used to manufacture highly efficient heat sink materials and is widely applied in scenarios with high heat dissipation requirements such as LED lights, power devices, microwave devices, and highly integrated electronic devices.

3. Chemical stability:

The chemical composition of diamond micro-powder is carbon. It has excellent chemical stability and can resist the erosion of harsh environments such as moisture, salt and chemical substances. This enables diamond micro-powder to maintain stable performance even in corrosive environments.

4. Versatility:

Diamond micro-powder can not only be used for grinding and polishing, but also as a functional material applied in multiple fields. For instance, by taking advantage of its thermal and electrical properties, new materials that can enhance thermal conductivity and reduce thermal expansion can be fabricated. When mixed into metal sheets, it can produce a new type of sheet material with high thermal conductivity, low thermal expansion and light weight, which is applied in the electronics industry.

5. Particle size controllability:

Diamond micro-powder can obtain the required particle size distribution through different classification methods to meet the demands of various application fields. For example, diamond micro-powder with narrow particle size distribution and uniform product particle size can be obtained through the gas flow classification method.

6. Environmental Protection and Sustainability:

Diamond micro-powder, as an artificial material, has a relatively environmentally friendly production process and does not generate harmful substances during use. In addition, with the continuous advancement of technology, the recycling and reuse technology of diamond micro-powder is also constantly developing, which is conducive to the sustainable utilization of resources.
