FO is the revolutionary abrasives researched and developed, gone into operation by Japan FUJIMI Company in 1950, named as the special optical emery. It is special used for grinding and polishing optical instrument, silicon crystal, chip and any material with hardness between 7-8. This special micro powder with unique properties, FO has accounted for 70% of world market and 95% of Japanese market. It has more than 60 years since coming into season. There is no other enterprises that can produce a great quantity abrasives competing with “FO” in Japan and the world up to now.

The developer of Chinese “FO” is Fan Donghai in the field of abrasives who can smelt silicon carbide, brown corundum, white corundum, single crystal corundum, high alumina corundum, abrasives processing and micro powder production, and can design the production process, having more technologies.

There is a kind of new variety in the field of national abrasives through many years research, and it also stops a gap in this part.

The production process and technical conditions of “FO” have the special demands. It belongs to a high and new technology. The value added of the products is very high. Meanwhile, it is a great and irreplaceable product.

The enterprises that imported “FO” can completely use the domestic products after its going into operation. The quality of the domestic “FO” is steadier and more effective. It also can greatly reduce the cost. So this is good news for the enterprises that use “FO” products.
