| Abstract: | Method of determinating of tungsten trioxide in artificial scheelite is described.Test sample is dissolved in hydrochloric acid,and concentrated to fume white smoke at low temperature in the solution of perchloric acid and nitric acid under the condition of seed crystal technique,the tungstenic acid is separated,and it is filtrated,washed,melted,vaporized,burnt,metaged and calculated,and the tungsten trioxide in filtrate and draff is determinated in photometric determination and then revise result. |
