Qual Diamond’s Hydroqual HAM diamond slurries are formulated using an advanced hydro-based matrix. The slurries are consisted of high-pressure high-temperature monocrystalline diamond particles suspended in a hydro-based matrix. Prolonged suspension is made possible by a proprietary surface modification technology, which prevents diamond particles from agglomerating. This specially formulated slurry is resistant to evaporation when exposed to air, making it an excellent alternative to oil-based diamond slurry. HAM slurries are ideal for lapping and polishing of materials high on the Mohs scale: sapphire, silicon carbide, tungsten carbide, spinel, etc.
