  • Method for preparing oxygen compounds of antimony with metals
    Patent number: 3984353
    Abstract: This invention relates to the method for preparing oxygen compounds of antimony with metals.According to the invention, the method for preparing oxygen compounds of antimony with metals consists in oxidation of antimony trioxide by hydrogen peroxide at a temperature from 40.degree. to 100.degree.C to form a suspension of hydrated antimony pentoxide and interaction of the obtained suspension of hydrated antimony pentoxide with metal compounds with subsequent drying ad calcining at temperatures from 300.degree. to 700.degree.C.The invention can be employed in the manufacture of metal oxide-antimony catalysts and metal-oxide resistor materials.

  • Method for producing granulated porous corundum
    Patent number: 3950507
    Abstract: The invention relates to a method for producing granulated porous corundum having a homogeneous porous structure with a total pore volume of 0.3 to 1.0 cm.sup.3 /g and predominant pore size of 5000 to 30000 A. The method comprises subjecting the granules of active alumina or aluminum hydroxide having a porous structure with a total pore volume of 0.3 to 1.0 cm.sup.3 /g and pore size of 20 to 5000 A to heat treatment by increasing the temperature from 20.degree.C to 700.degree.C during a period of at least 0.5 hour, thereafter the granules are heat treated at a temperature range of from 700.degree.C to 1000.degree.C for at least 0.5 hour, and then at a temperature range of from 1000.degree.C to 1400.degree.C for at least 0.5 hour, the heat treatment in the temperature range of from 20.degree.C to 1000.degree.C being carried out in an atmosphere of hydrogen fluoride which is present in amounts of from 0.01 to 2.0 percent of the weight of active alumina.
