  • Method for producing alumina and alumina-zirconia abrasive material
    Patent number: 4059417
    Abstract: Abrasive granules are produced from alumina or an alumina-zirconia mixture by melting the oxide material and rapidly cooling the melt. To control the solidification velocity, the melt is cast into a molten chloride of Na, Ca, Ba, Mg or mixtures thereof to cool the oxide material melt, the chloride is separated from the cooled and solidified oxide material, and thereafter abrasive granules are produced from the solidified oxide material.

  • Process for the preparation of agglomerated vanadium oxides
    Patent number: 4035476
    Abstract: Agglomerated vanadium oxides of the formula V.sub.2 O.sub.x, wherein x is between 3.8 and 4.6, are prepared by thermally decomposing ammonium polyvanadate at 600.degree.-900.degree. C and permitting the resultant solid decomposition products and reducing gases to react. The reducing gases displace the air and/or scavenging gas in the reaction zone.
