Applications of Nano Diamond Micro-powder in Polishing Realm

Diamond powder as a kind of superhard materials in the industry, is widely used in cutting, grinding, wear-resistant coating, polishing, etc. Now we will introduce the applications of nano diamond micro-powder in the polishing realm.

We all know that some countries such as Europe, the United States and Russia study nano diamond early with the production capacity of nanometer diamond polishing liquid and polishing paste, while in our country, we have just started to research in the field of nano diamond polishing liquid. Although there is still a gap compared with abroad, we believe that we must be able to have great breakthrough in this field as long as we continue to research actively.

Nano diamond polishing compound has excellent performance, widely used in semiconductor wafer polishing, computer hard disk substrate, computer head polishing, precision ceramics, artificial crystals, cemented carbide, gem polishing and other fields. Russia uses nano diamond to polish quartz, optical glass, etc. whose the roughness of polished surface has reached 1nm. The applications of nanometer diamond show many advantages. For example, because it is super fine and super hard that make the problem of optical polishing solved.

Fine polishing is one of the most difficult problems in optical polishing. The original process method is to use the abrasive repeatedly which will need a few hours, and the efficiency is very low. But now we can use nano diamond that makes the polishing speed greatly increased. The time for polishing the same artifacts only is from more than ten hours to a few minutes, whose efficiency is improved about hundreds of times. Nano diamond has been applied in various fields and its application range is still expanded in the future.
