Antimony oxychlorides Sb^Ch and SbOCl are a kind of inorganic flame retardants with high efficient retardancy. The acidic hydrometallurgy technology of antimony is a new process for treating complex antimony ores or concentrates and fine processing the antimony products. By using intermediate products in the acidic hydrometallurgy of antimony as raw materials, the new processes for preparing Sb^sClj and SbOCl flame retardants were developed in the doctorial thesis. The flame retardancy and flame ...
