BLIT Chemical supplies Sodium Pyroantimonate CAS 12507-68-5 (NaSbO₃·H₂O) as a fine chemical raw material for solar photovoltaic glass, ultra-white glass, optical glass, and high-end glass applications. As a Sodium Pyroantimonate manufacturer in China, BLIT Chemical provides white powder products with controlled Sb₂O₅ content, customized fineness options, and quality documentation support for global glass manufacturers.

Compared with traditional antimony trioxide systems, Sodium Pyroantimonate provides pentavalent antimony directly, reducing the additional oxidation conversion process from trivalent antimony to pentavalent antimony during glass production. This can help reduce sodium nitrate consumption, minimize antimony loss during processing, and support more consistent production performance.

BLIT Chemical operates production facilities for antimony-based chemicals, including approximately 20,000 tons/year Sodium Pyroantimonate capacity, with additional production capacity for Sodium Metantimonate and Antimony Trioxide. The product has been supplied to overseas markets including India and Southeast Asia, where it is used by photovoltaic glass manufacturers and other glass industry customers.

Приложения

Solar Photovoltaic Glass

Sodium Pyroantimonate is widely used in solar photovoltaic glass production as a clarifying and decolorizing agent.

For photovoltaic glass manufacturers, optical performance, transparency, and production stability are important factors. Sodium Pyroantimonate helps support the production of ultra-white solar glass where low coloration and high light transmission are required.

BLIT Chemical supplies Sodium Pyroantimonate powder with controlled quality and adjustable fineness to meet different glass production requirements.

Ultra-White Glass and Optical Glass

Sodium Pyroantimonate is suitable for high-grade glass applications requiring improved clarity, appearance, and stable physical properties.

Typical applications include:

• Ultra-white glass
• Optical glass
• Specialty glass
• High-end architectural glass

Glass Clarifying and Decolorizing Agent

High-End Tableware Glass

Правила использования

BLIT Chemical recommends customers evaluate Sodium Pyroantimonate according to their glass composition, furnace conditions, and production requirements before bulk application.

For glass manufacturers, particle size and powder dispersion are important during raw material preparation. Customized fineness selection can help improve mixing uniformity with other glass-forming materials and support consistent distribution during the melting process.

Before large-scale production, customers are recommended to conduct production trials to evaluate:

• Compatibility with existing glass formulations
• Mixing uniformity with other raw materials
• Influence on glass clarity and color performance
• Adjustment of addition ratio according to furnace conditions

During continuous glass production, maintaining stable raw material quality and particle size distribution can help support consistent product performance.

BLIT Chemical can communicate with customers regarding fineness requirements, specifications, and application conditions according to different glass manufacturing processes.
