We supply high‑purity low iron dolomite (Fe2O3<100 ppm) specifically engineered for solar and photovoltaic (PV) glass manufacturing. Our material is suitable for high‑transmittance cover glass where low Fe₂O₃ and controlled composition are critical for optical performance and energy yield.

We have established long‑term business partnerships with low iron dolomite mining operations in Guangxi Province and other key regions in China. This network enables us to source material with consistent quality and to meet bulk‑order requirements for integrated solar‑glass producers.

Typical Technical Specifications (for reference)

For solar‑glass‑grade applications, low iron dolomite is generally supplied to meet the following ranges (exact values can be tailored to your formula):

• Fe₂O₃ (Iron Oxide): ≤ 0.006–0.01% ( 60–100 ppm)
• CaO: ~30–33%
• MgO: ~20–22%
• SiO₂(<0.5 %), Al₂O₃, TiO₂: minimised to reduce refractory wear and coloration
• Total acid insolubles: < 2% (preferred)
• Size: < 2.8 mm; can be crushed/screened to your required fraction (e.g., lumps, chips, or graded sizing)

We can supply low iron dolomite as per your specifications, including size distribution, chemical‑composition tolerances, and moisture limits, to seamlessly integrate into your solar‑glass batch formulation.

Why Choose Our Low Iron Dolomite?

• Low‑iron dolomite for solar glass: Optimised Fe₂O₃ content to maintain high solar transmittance and minimal green tint.
• Stable sourcing:  Having mining units in Guangxi Province and other locations in China ensure reliable supply and traceability.
• Custom specifications: We manufacture and supply low iron dolomite tailored to your CaO/MgO targets, particle‑size distribution, and processing requirements.

If you share your typical solar‑glass batch formula or target ranges (Fe₂O₃, CaO, MgO, SiO₂ and size), we can provide a formal specification sheet and trial‑quantity offer.
