Applications of Polycrystalline Diamond Slurry in Precision Material Processing

Traditional polishing fluids often struggle with unstable performance, leading to surface haze, inconsistent removal rates, and sub-surface damage left after grinding.
Our Polycrystalline Diamond Slurry is engineered to solve these issues with controlled particle morphology and stable dispersion chemistry.

Polycrystalline Diamond Slurry is widely used in sapphire polishing slurry processes and advanced semiconductor wafer finishing where ultra-smooth surface quality is required. It also performs effectively in SiC lapping slurry applications, especially for hard and brittle materials requiring controlled material removal.
