Introduction
With the surge in demand for precision machining in high-end manufacturing, diamond powder - especially diamond powder for grinding dedicated to high-precision grinding - is ushering in technological breakthroughs and market expansion. The world's leading diamond manufacturers are promoting the application and upgrading of this superhard material in key industries such as semiconductors, optical devices and aerospace by optimizing production processes and surface treatment technologies.
Diamond powder: the "hidden champion" of precision manufacturing
Diamond powder has become a core material in the field of precision grinding, polishing and coating due to its unparalleled hardness (Mohs hardness 10) and excellent thermal conductivity. In recent years, with the development of 5G, new energy vehicles and microelectronic components, the market demand for nano-level diamond powder for grinding has soared. According to industry reports, the global diamond powder market size will grow at an average annual rate of 9.2% from 2023 to 2028, of which the Asian market accounts for more than 40%.
Technological breakthrough: Surface modification technology improves grinding efficiency
To meet the requirements of high-end customers for processing consistency and efficiency, leading diamond manufacturers are focusing on two major innovation directions:
1. CVD synthesis technology: Prepare high-purity single crystal micropowders through chemical vapor deposition (CVD) to reduce the damage of impurities to the workpiece surface.
2. Surface functionalization: Use metal plating (such as nickel, titanium) or hydrophilic modification to enhance the adhesion between micropowder and binder and extend tool life.
Capacity expansion and green manufacturing go hand in hand
To cope with the supply-demand gap, major diamond manufacturers in China, India and Europe have expanded production. For example, [Company Name] recently announced an investment of US$200 million to build an intelligent production line, aiming to increase the annual production capacity of diamond micropowder for grinding to 500 tons. At the same time, the industry is accelerating the promotion of environmentally friendly processes to reduce carbon footprint by recycling industrial diamond waste.
Application scenarios are expanding: from traditional cutting to semiconductor lithography
In addition to traditional carbide tool grinding, nano-scale diamond powder is penetrating into cutting-edge fields:
• Semiconductor wafer cutting: avoid silicon material edge collapse and improve chip yield.
• Optical lens polishing: achieve sub-nanometer surface roughness to meet the needs of AR/VR lenses.
• Aerospace coating: enhance the high temperature wear resistance of turbine blades.
