Global Diamond Powder for Polishing Compound Market Strategic Research Report

Scope of the Report

The global Diamond Powder for Polishing Compound market size is predicted to grow from US$ 74.35 million in 2025 to US$ 115 million in 2032; it is expected to grow at a CAGR of 6.5% from 2026 to 2032.

Diamond Powder for Polishing Compound is a fine synthetic diamond material engineered specifically for formulating polishing compounds and slurries, providing extremely high hardness, controllable particle size distribution and excellent surface finishing capability for precision processes. Its key advantages include much higher cutting and polishing efficiency than conventional abrasives, long service life in continuous operations and the ability to deliver uniform, scratch-free surfaces required in consumer electronics, semiconductor wafers and high-precision mechanical parts. In 2024, production was approximately 959 tons and the average price was USD 73,000 per ton. The industry’s capacity utilization rate in 2024 was about 60% and the average gross margin was around 35%. In the upstream segment, critical inputs include high-purity graphite and jet milling equipment, with representative suppliers such as GrafTech and Hosokawa providing carbon materials and fine grinding systems that determine base quality and cost. The midstream stage focuses on synthetic diamond synthesis or selection, crushing and jet milling, precision classification, particle shaping and surface treatment, followed by formulation into polishing compounds tailored to different substrates and roughness targets. Downstream, diamond powder for polishing compound is widely used in consumer electronics, semiconductor and mechanical processing, with companies such as Apple, Samsung, Intel, TSMC and Bosch.

The market outlook for diamond powder for polishing compounds is highly positive as precision manufacturing industries continue to demand superior surface quality, tighter tolerances and higher production efficiency. The rise of advanced semiconductor nodes, increasingly compact consumer electronics and high-performance mechanical systems requires polishing materials capable of delivering nanometer-level finishes with minimal defects. Diamond powder offers unmatched hardness, thermal stability and abrasiveness, enabling faster removal rates and more consistent surface results than any conventional abrasive. As device architectures become more complex and materials such as sapphire, ceramic substrates and wide-bandgap semiconductors gain wider adoption, the reliance on high-purity diamond polishing compounds will intensify. With ongoing improvements in particle classification, shaping and surface modification technologies, diamond powder is expected to maintain strong long-term growth and become an even more critical enabler of next-generation electronic and optical manufacturing.
