Abstract
The invention relates to a process for obtaining photostable valentinite and to valentinite obtained by said process. The process consists in carrying out a basic hydrolysis of antimony trichloride at a temperature comprised between about 80.degree. and 100.degree. C. with a weight ratio of H.sub.2 O/Sb.sub.2 O.sub.3 equal to or greater than about 10. Obtention of photostable valentinite.
