摘要：
There is provided a process for producing a particulate iron-antimony containing oxide composition having high compressive strength, comprising the steps of: providing an aqueous slurry containing iron ions, nitrate ions and antimony trioxide; adjusting the slurry to a pH value in the range of 0.5 to 3 as measured at 40.degree. C.; heating the slurry; spray-drying the heated slurry; and calcining the resultant particles.
