GOYENCHEM-SB Glass Grade Antimony Trioxide CAS NO. 1309-64-4

GOYENCHEM-SB-2 Antimony Trioxide

(High-Purity Sb₂O₃ for Glass Clarification, Ceramics & Electronics)


 


Product Description

GOYENCHEM-SB-2 is a high-purity antimony trioxide (Sb₂O₃) designed for glass,

ceramics, and electronic applications.

It is widely used as a glass clarifying agent and defoaming additive,

helping eliminate bubbles during the melting process and improving overall transparency.

With high whiteness and low impurities, SB-2 ensures stable performance in high-temperature processing environments.
