Optics and precision engineering also contribute significantly, with rising demand for defect-free surfaces in medical devices, aerospace components, and defense technologies. Supply-side factors include the availability of synthetic diamond powders, which now dominate production due to cost efficiency and consistency. However, volatility in raw material prices and stringent environmental regulations on chemical waste management present ongoing challenges.
Technological advancements are reshaping the market. Recent breakthroughs in photocatalysis-assisted chemical mechanical polishing (PCMP) have demonstrated the ability to reduce diamond substrate roughness from Ra 33.6 nm to Ra 2.6 nm within eight hours, a performance improvement that directly enhances product quality and throughput. Integration of hydrogen peroxide and phosphoric acid in slurry formulations under UV exposure exemplifies how chemical innovation is improving efficiency while reducing mechanical damage. Such developments are critical for industries where surface integrity directly impacts performance and reliability.
Regionally, Asia Pacific leads the market, driven by its dominant semiconductor manufacturing base in China, Taiwan, South Korea, and Japan. North America and Europe remain important due to strong aerospace and defense applications, while emerging markets in Southeast Asia are attracting new investment in electronics manufacturing. Strategic consolidation is also shaping the competitive landscape. Hyperion Materials & Technologies’ acquisition of Premium Diamond Solutions SA in 2022 expanded its European footprint and reinforced its global supply capabilities. For investors, the combination of rising semiconductor demand, ongoing R&D in slurry chemistry, and consolidation among key players signals a market with strong long-term growth potential and increasing barriers to entry.

Type Analysis
Water-soluble slurries command the market by type, accounting for a substantial 62.8% share in 2025. This dominance stems from their widespread use in precision polishing applications across the electronics, optics, and automotive sectors. Their effectiveness in creating high-quality surface finishes, combined with environmental advantages and easier cleanup, makes them the preferred choice for manufacturers adhering to stricter sustainability standards. The demand for water-soluble products is projected to grow at a compound annual growth rate (CAGR) of approximately 8.5% through 2030.
Conversely, oil-soluble diamond slurry holds a more specialized market position. It is primarily used in heavy-duty machining and grinding operations that require superior lubricity and a longer working life. While valuable for specific industrial tasks, its adoption is constrained by environmental regulations and complex handling requirements associated with oil-based products. The market is witnessing a clear and sustained movement toward water-soluble formulations as companies prioritize both performance and responsible manufacturing practices.
