Synthetic Cryolite

Synthetic cryolite is supplied at Na/Al molar ratios of 1.5:1 to 2.85:1 (sub-stoichiometric to stoichiometric). Smelter-grade is sized to D50 ≈ 30 µm (free-flowing fine powder); welding-flux grade is sized to 100–200 µm granular. Custom Na/Al ratios and PSDs are made-to-order.

Smelter-grade cryolite assays F 52% min, Al 12.5–13.0%, Na 30–32%, with SiO₂ < 0.25%, Fe₂O₃ < 0.05%, P₂O₅ < 0.02%, and SO₄ < 0.5%. Bulk density is 0.85–1.05 g/cc. Each consignment is supplied with full XRF and wet-chemistry COA.

Cryolite is regulated under UN 3288, Class 6.1 PG III. We ship in 1000 kg FIBC jumbo bags or 25 kg laminated HDPE bags with full IMDG / ADR / DGR documentation.

Synthetic Cryolite is supplied in HDPE woven bags with inner LDPE liner (25 kg / 50 kg net), HDPE drums (25 / 50 / 250 kg), and FIBC jumbo bags (500 / 1000 kg) for solid grades. Liquid grades ship in HDPE-lined steel drums (250 kg) or 1000 L IBC totes. Custom packaging — including nitrogen-blanketed, moisture-tight, or food-grade containers — is available on request.

Standard MOQ is 1 metric tonne for solid grades and 200 kg for liquid grades; pilot quantities of 5–25 kg are available for R&D qualification. Stock items dispatch within 7–10 working days from confirmed PO. Made-to-order grades and large export consignments require 3–4 weeks. Indian deliveries by road typically reach 4–7 days; export FCL shipments depend on destination port.
