Catalysts or carriers which consist essentially of monoclinic zirconium dioxide

Catalysts or carriers which consist essentially of monoclinic zirconium dioxide are prepared by pecipitation of zirconium salts with ammonia, by adding a zirconyl nitrate or zirconyl chloride solution to an aqueous ammonia solution at a decreasing pH from 14 to 6 and drying, calcining and pelletizin...
