【Abstract】 Based on the Ostwald rule of phase transformations, the reason why cubic antimony white can′t be produced from the hydrolysis neutralization of SbCl 3 is interpreted: during the neutralization transforming process of antimony oxychloride(Sb 4O 5Cl 2), the orthorhombic antimony white, the meta stable phase at low temperature, is firstly formed, and exists stably all along in fact, because the system can′t supply enough energy to move the atoms for phase transformations. Adding a little ligand such as EDTA, tartrate before neutralization to change the transferring reaction course, is the best method of synthesizing cubic antimony white (Sb 2O 3) by hydro process.
