Description

Sodium Antimonate is a high-purity inorganic compound primarily used as an effective opacifier and fining agent in the production of specialty glass and ceramics. Its value lies in its ability to provide superior clarity, brilliance, and chemical durability to glass products while also facilitating the removal of bubbles during the melting process. This makes it an essential raw material for manufacturers in the glass, enamel, and electronics industries seeking to enhance product quality and performance.

Application

• As a key opacifying agent in the manufacture of opaque glass, glassware, and ceramic glazes.
• As a fining agent in glass production to remove gaseous inclusions and improve clarity.
• In the formulation of flame-retardant synergists for plastics and textiles, often in combination with halogenated compounds.
• As a precursor in the synthesis of other antimony-based chemicals and catalysts.
• In the production of specialty pigments and ceramic colors.
• As an additive in the electronics industry for certain types of optical glasses and components.
