3] samples were prepared by the sol-gel method using titanium (IV) butoxide (Aldrich 97%), cobalt nitrate (Reasol 99%) and tungstic acid (Fluka 99%) as precursors: 44 mL of 1-butanol (Aldrich 99.
The residue (silica and tungstic acid) was washed with a small volume of hot (1+99) H2SO4, followed by water; the volume was made up to the mark with deionized water.
The patentee produced the purified tungsten by placing tungstic oxide in a gas furnace, allowing oxygen, carbon, and impurities to escape.
The acid liberated the whole of the tungstic acid from the tungstate, and practically all tungstate was taken down by the protein precipitate leaving sufficient excess acid to give a filtrate with a pH between about 3.
The resulting tungstic acid was reacted with ammonia to produce ammonium para-tungstate.
Another Swedish chemist, Carl Wilhelm Scheele (1742--1786), confirmed Cronstedt's suspicion in 1781 by isolating the oxide form of the mysterious metal and preparing from it a compound that he named tungstic acid.
The residue (silica and tungstic acid) was washed with a small volume (5mL) of hot (1:99) sulfuric acid, followed by water, the filtration and washing were collected in the same calibrated flask and the volume was made up to the mark with deionized water.
