CeO2 & Rare Earth Polishing Powders

Rare Earth, Silica & Al  Polishing Slurries 

Boron Carbide, Diamond Grinding Fluids 

Crystalline Silver Nano Wires

Cerium oxide, rare-earth and non-rare earth polishing powders remove material by mechanical abrasion, plastic flow and chemical interaction, making them uniquely effective at material removal when low surface roughness and ultra-clean surfaces are an imperative. Optimum fire temperature and particle shape,  narrow size distribution and additives to enhance material removal rate mean these formulations provide maximum cutting power, resistance to particle breakdown and high fluidity. In use for over a decade at leading factories around the globe. 

Hunan Haozhi slurries are the preferred choice when the task involves corrosion and roughness removal. Compared to competing products, the polished surface will not exhibit surface or subsurface damage, roll off or edge collapse. Use these slurries for trusted value and performance on precision optical components, ophthalmic, small and large flat prisms and reflectors, architectural & automotive glass, photo-masks, sapphire, silicon, crystals & aluminum. An extensive list of standard formulations offers a slurry for almost any application. Modifications available.

Diamond (mono crystalline and poly-crystalline) and boron carbide comprise the most thermally stable and hardest abrasive materials. Diamond's high thermal conductivity will pull heat energy away from the work zone into the high speed coolant, while boron carbide grit offers exceptional hardness & durability. Both are suitable for shaping, grinding and thinning of hard materials such as sapphire, ceramics and stainless steel. See our data pages for applications information and downloads. Custom formulations are available.


Crystalline silver nanowire, with length to diameter ratios exceeding 1000:1. When coated on plastic substrate (typically PET), the crystalline nano wires overlap, producing  transparent and highly conductive films, suitable for applications from flexible display glass, solar cells and touch screens to smart privacy glass.  Adhesive and ink formulations are used in a variety of electronics applications including flexible membrane switches and smart glass.
