What are the types of glass clarifying agents?

We are a manufacturer of glass clarifying agents, welcome to inquire!

There are four main types of glass clarifying agents, let me help you clarify them:

1. Oxide type clarifying agent

Representative substances: Cerium oxide (CeO ₂), Antimony oxide (Sb ₂ O3), Sodium nitrate, etc.

Mechanism of action: Decomposes and releases oxygen at high temperatures, promoting the merging and expulsion of bubbles.

Application scenarios: Widely used in construction, automotive, electronics, and daily glass manufacturing.

2. Sulfate type clarifying agent

Representative substances: sodium sulfate (saltpeter), barium sulfate, calcium sulfate, etc.

Mechanism of action: Decomposition produces O ₂ and SO ₂, promoting bubble growth and dissolution.

Application scenarios: Commonly used for high-temperature glass such as bottle glass, flat glass, and beer bottles.

3. Halide type clarifying agent

Representative substances: Calcium fluoride (CaF ₂), sodium chloride, ammonium chloride, etc.

Mechanism of action: Reduce the viscosity of glass melt, making it easier for bubbles to rise and be expelled.

Application scenario: Suitable for special glass manufacturing.

4. Composite clarifying agent

Representative substances: arsenic free composite clarifying agent, arsenic based/arsenic antimony based/cerium based composite clarifying agent, etc.

Mechanism of action: The synergistic effect of oxygen clarification, sulfur clarification, and halide clarification is comprehensively utilized.

Application scenario: It is a trend in the glass industry to achieve arsenic free formulations, suitable for high-end glass manufacturing.

I hope this information can help you! If you need more specific application suggestions, feel free to let me know at any time.
