In the brilliant starry sky of materials science, industrial diamonds shine like a dazzling star, becoming an indispensable key material in modern industry with their extraordinary properties.
The hardness of industrial diamonds is known as the "king of hardness," reaching the highest level of 10 on the Mohs hardness scale, with an absolute hardness 1000 times that of quartz, 150 times that of corundum, and 10 times that of steel. This unparalleled hardness allows it to easily break various rock layers and process hard alloys, ceramics, etc., truly achieving the ability to "cut iron like mud."
Its wear resistance is equally outstanding. In the electronics industry, the lifespan of diamond wire drawing dies is 250 times that of hard alloy wire drawing dies; when honing automotive engine cylinders, one piece of diamond oil stone is equivalent to 300 ordinary oil stones. With high wear resistance, tools made from industrial diamonds can significantly extend service life and reduce production costs.
Industrial diamonds also possess high thermal conductivity, with the highest thermal conductivity among natural materials, reaching 2300W/(m·K), which is 4 times greater than silicon carbide, 13 times greater than silicon, and 43 times greater than gallium arsenide, and 4 to 5 times that of copper and silver. This property makes it an ideal material for heat dissipation in electronic devices, effectively solving the high heat problem during the operation of electronic equipment and ensuring stable operation.
In addition, industrial diamonds have extremely high processing precision. Using diamond turning tools to finely process copper and aluminum parts and cutting end faces can achieve a processing precision of 0.5 microns, far exceeding that of ordinary turning tools. At the same time, it can improve material utilization. When processing precious and brittle hard materials, the cutting seam is narrow, and the cutting precision is high. For example, when beryllium oxide ceramics are processed with diamond tools, the metal recovery rate can increase by nearly 1 time, and costs can be reduced by 40%.
Among many industrial diamond production enterprises, Zhongjing Henan Diamond stands out as your quality choice. Zhongjing Henan Diamond has established a scientific and complete product testing system, providing optimized diamond combinations that better match tool usage for customers through sorting, mixing, and testing. Its products cover various types, whether diamonds used for cutting and grinding or diamond micropowders with perfect crystal shapes, all meet the rigorous demands of different industrial fields with excellent quality, helping enterprises improve production efficiency and product quality, and seize opportunities in fierce market competition.

In the global industrial sector, industrial diamonds, with their high hardness, high wear resistance, and high thermal conductivity, have become indispensable basic materials in many key industrial processes. They are widely used in core industries such as semiconductors, aerospace, and machining, playing a crucial role in the development of modern industry.
Expectations of the Semiconductor Industry for High-Quality Diamonds (Part 1)
Band gap: determined by the electronic states and atomic configurations of semiconductors, it reflects the energy required for the valence electrons of the atoms that make up this material to be excited from a bound state to a free state; the band gap is an important characteristic parameter of semiconductors. A band gap of zero indicates a metal, a large band gap (generally greater than 4.5 eV) indicates an insulator, and a medium band gap indicates a semiconductor.
Expectations of the Semiconductor Industry for High-Quality Diamonds (Part Two)
The conduction mechanism of semiconductor materials is achieved through two types of charge carriers: electrons and holes, which are classified as N-type and P-type. Diamond, as a group IV element, can be viewed as having a crystal structure formed by two face-centered cubic structures translated along the body diagonal by 1/4 of the lattice constant. Carbon atoms bond with four neighboring carbon atoms through covalent bonds using sp3 hybrid orbitals, forming a tetrahedral structure. By doping diamond with appropriate elements, its electrical properties can be altered, allowing it to be widely used as a semiconductor material in electrical devices.
