Global Diamond Slurries Market Strategic Research Report

Scope of the Report

The global Diamond Slurries market size is predicted to grow from US$ 140 million in 2025 to US$ 203 million in 2032; it is expected to grow at a CAGR of 5.6% from 2026 to 2032.

The conventional definition of slurry is a mixture of water and small particles of a solid. The particles are not normally suspended in the liquid and are maintained in suspension by agitation during the use of the slurry. Diamond Slurry is that the particles are micron sized diamond particles and the liquid (carrier vehicle) can be oil or water based. Diamond Slurries are used for polishing materials that require a mirror finish. They are often used in metallurgical specimens, carbide dies, carbide seals, spectacle glass industry, semiconductor industry and for polishing diamonds, etc.

The diamond slurries market is developing rapidly due to various factors. The processes of wafer, chip, packaging, etc. have extremely high requirements for surface roughness. Diamond polishing fluid is suitable for ultra-precision polishing of materials such as Si, SiC, GaN, etc. The rise of technologies such as 5G, AI, and autonomous driving promotes more advanced semiconductor manufacturing, and the demand for high-quality polishing fluid increases.

The precision optics and medical device industries usediamond slurries with nano-scale particle size and strong controllability. The demand for high-efficiency and low-damage polishing fluids is growing, which promotes environmentally friendly, water-based diamond polishing fluids to replace traditional oil-based products.

Companies in Europe, the United States, South Korea, and Japan, such as Engis Corporation, Saint-Gobain, Lapmaster, Kemet International, Iljin Diamond, Fujimi Corporation, Pureon, Asahi Diamond, etc., occupy the high-end market. In terms of output value, the top five global manufacturers (Engis Corporation, Saint-Gobain, Lapmaster, Kemet International, Iljin Diamond) will account for 58.89% of the market in 2024.
