APT 361

APT is the abbreviation for ammonium paratungstate. It may be reduced to tungsten powder (W powder) by hydrogen reducing agent. There are two processes – direct reduction and secondary reduction. 1. Direct Reduction Adopt H2 to directly reduce APT to W powder. Calcination and reduction are generally completed in a furnace tube where is controlled by multiple temperature zones, and the obtained W powder has the characteristics of fine grain size and dark gray color. However, this producing method isn’t…
