Industrial diamond has a wide range of applications, broad development prospects

Industrial diamond includes diamond single crystal and diamond micropowder, among which diamond micropowder is micron or submicron diamond powder formed from diamond single crystal through crushing, ball milling and other processes. The steady growth of demand for industrial diamonds mainly comes from the traditional processing field, as well as the advanced manufacturing field mainly based on photovoltaic new energy and third-generation semiconductor applications.

It is estimated that by 2025, the global industrial diamond market size will be 8.027 billion yuan, with a compound annual growth rate of 7.53%. Among them, the industrial diamond market size in my country will reach 7.225 billion yuan, including the diamond single crystal market size of 4.613 billion yuan and the diamond micropowder market size of 2.612 billion yuan. billion.

The demand for industrial diamonds in the traditional processing field has maintained a steady growth for a long time.

 

(1) Building materials and stone materials: The real estate industry is one of the major industries in my country. Its investment completion has increased from 6.2 trillion yuan in 2011 to 14.1 trillion yuan in 2020, maintaining rapid growth for a long time. Future infrastructure investment and real estate development scale The expansion will continue to drive the growth of demand for diamond tools for building materials processing.

(2) Exploration and mining: The material advantages and technical advantages of diamond single crystals are more significant in exploration and mining. In the future, the application level in deep hole drilling will be further improved, and the increase in the number and difficulty of mineral mining will drive the continuous growth of demand for diamond single crystals.

(3) Machinery manufacturing: Artificial diamond is an indispensable raw material for cutting tools in the machinery manufacturing industry. Cutting tools account for about 90% of the entire machining process. They are widely used in automobiles, motorcycles, machine tools, general machinery, Mold, aerospace, construction machinery and other application fields. According to QY Research, the market size of cutting tools will reach 199.9 billion yuan in 2026, with a compound annual growth rate of 3.91%.

The large-scale application of photovoltaic new energy and third-generation semiconductors in the field of advanced manufacturing will breed emerging demand.

(1) Photovoltaic new energy: Since 2017, with the breakthrough of diamond wire saw cutting technology, the cost has dropped rapidly, and diamond micropowder has been widely used in the cutting field of photovoltaic monocrystalline silicon and polycrystalline silicon materials, effectively replacing traditional mortar and silicon carbide mortar slices . According to CPIA estimates, the global installed capacity of photovoltaics will increase from 170GW to 330GW from 2021 to 2025. According to the diamond wire 375,000 km/GW and the capacity ratio of 1.32, the global demand for silicon wafers will reach 436GW in 2025, and the demand for diamond wire will reach 436GW. It will reach 163.35 million kilometers, with a compound annual growth rate of 23.90%.

(2) Third-generation semiconductors: The third-generation semiconductors are widely used in new energy vehicles, high-speed transportation, 5G communications and other fields. The silicon carbide material has high hardness, and it needs to be used in several production processes such as crystal cutting, wafer grinding, and wafer polishing. Processing with diamond micropowder or related products. According to CASA Research, the international silicon carbide automotive market will grow at a compound annual growth rate of 38%, and will exceed 10 billion yuan by 2025.
