Amorphous Boron Powder
Our amorphous boron powder is produced based on the hot-magnesium reducer foundation. With the new hot-explosive and self-extend technology ,we can produce different specifications of boron powder 86-89%, 90-92%, 93-94%, 95-97% at one time. This product can be produced on a large-scale, and the product has achieved the international advanced level, obtained consistent high praise from domestic and foreign users.
The reliability, the uniformity and high quality of amorphous boron powder can apply in the field of spatial technology, the superconductivity, the auto safety aerocyst and so on.

Atomization Magnesium Powder
|
||||
|
Characteristic: Under the inert gas protection, uses the centrifugal atomization technology with the 99.90% magnesium ingot melt to turn into the liquid, processes into the silver-white color, granulated powder through many working procedures. The active magnesium has high content, high spherical- rate, big bulk density, good fluidity and small relative surface, thus has a incomparable superiority which the Ground magnesium powder do not have.
|
||||
|
Use: industries of aviation and space, national defense, petrochemical, new function material, medicine, pyrotechnical, food and advanced functional materials.
