Applications and Quality Control of Diamond Micro Powder

At present, domestic diamond micro powder is widely used in hard alloy, high alumina ceramic, optical glass, instrument gems, semiconductor and other hard and brittle materials, for grinding, lapping and polishing, which is an important and indispensable product in defense industry, mechanical industry, optical industry, electronic industry, scientific experiments and other precision machining.

The national large diamond enterprises gather in Henan, because it has abundant raw materials of superhard materials. Some large-scale production enterprises of superhard materials are also concentrated in Henan, including Henan Yuxing Sino Crystal Micron Diamond Co., Ltd., Jinxin Abrasives Co.,ltd., etc., so Henan is a large production area of diamond micro powder.

How to evaluate the quality of micro powder, which is a common concern to diamond micro powder manufacturers and users. Practice shows that it must follow a strict control on the following four indicators to get good quality diamond micro powder: A, The size and content of coarse particles; B, The particle size distribution; C, The particle shape; D, The strength of diamond raw materials.

In recent years, with the rapid development of high and new technology abroad, the demand for diamond micro powder increases, used for processing electronic materials, all kinds of precious stones, fine ceramics, optical glass, precision bearings, seals and other fields, and it also has higher and higher quality requirements for diamond micro powder.
