Product Description

Product Description

1. Product Overview

Antimony trioxide (Sb2O3, Mr291.50) is a dual-type substance including cubic crystal and monoclinic crystal type. For different crystal form, the density and refractive index also slightly differ. The density and refractive index of cubic crystal is 5.2 and 2.087, respectively while is 5.67 and 2.18 for the monoclinic crystal, respectively. The Sb2O3 commonly derived from hydrolysis of SbCl3 is rhombic crystal can burn to red heat in an inert gas or in vacuum and can generate square crystal upon sublimation.
