99.5% industrial-grade potassium nitrate powder is a dedicated raw material for professional glazed ceramic processes

Our 99.5% industrial-grade potassium nitrate powder is a high-quality raw material used in glaze ceramic processes. It features excellent purity, rapid dissolution, and stable reactivity. As a key flux and oxidizer in ceramic glazes, this product can effectively lower the glaze melting temperature, enhance color development, improve glaze surface smoothness, and help ceramic manufacturers improve product quality and production efficiency.

Our core product advantages

Outstanding glaze effect

• Enhance color saturation: As a high-quality oxidant, ensure that metal oxides in ceramic glazes fully display their colors.
• Improve glaze flatness: Promote uniform glaze melting and reduce glaze defects.
• Enhance gloss: Endow the glaze with a natural and bright luster effect

Stable process performance

• Fast dissolution: Fine powder form is easy to disperse and dissolve in the glaze slurry.
• Uniform melting: Evenly distributed in the glaze material, ensuring stability between batches.
• Lower firing temperature: Effectively reduces the melting temperature of the glaze material, saving energy costs

Strict impurity control to meet high-end demands

The coloring ions such as iron (Fe) and chromium (Cr) are subject to extreme control, with their contents strictly controlled below 10ppm and 2ppm respectively. This is particularly suitable for the production of ultra-clear glass, optical glass and crystal glass, which have strict color requirements.

Economical and practical

• High cost performance: Industrial-grade purity balances performance and cost.
• Easy to use: Can be directly added to the glaze formula.
• Stable storage: Not prone to caking, easy to preserve and use
