Ceramic and glass buyers decide on chemistry, not on adjectives. Every product page here is built around the assay — Fe₂O₃, Na₂O, K₂O, Al₂O₃ — plus bulk packing and port, because that is what a ceramic body formulator actually needs to place an order.
Ceramic Minerals is a fully integrated non-metallic minerals company established in 2007 in Anyang, Henan. The company holds its own government-licensed mining licence and quarry containing over 120 million tonnes of verified nepheline syenite reserves — meaning decades of stable supply from one consistent deposit rather than a blend of purchased ore.
More than RMB 40 million has been invested in wet-process production lines. Multi-stage magnetic separation achieves Fe₂O₃ as low as 0.08%, a level the company states dry-process competitors cannot reach from the same ore. For ultra-white ceramic bodies and premium porcelain that iron figure is the whole decision — it determines whether the fired body comes out white or cream.
Annual production capacity is 250,000 tonnes. The product range covers three nepheline powder grades (GP20, K200, K100), two potassium feldspar grades (SY101, TX101 — K₂O 9-15%, Na₂O 3%, Al₂O₃ 17-19%, Fe₂O₃ 0.1-0.15%, flotation processed) and custom sodium feldspar (Na₂O 11%, Al₂O₃ 19.5%) — a lower-melting-point flux for glazes, wall tiles and glass.
The site sits 3 km from the expressway with fast access to Tianjin, Qingdao and Lianyungang ports. Packing is available in 1,200 kg jumbo bags and 50 kg bags. FOB and CIF terms are quoted worldwide, with samples, COA and a stated 24-hour response. The website runs in 13 languages — English, Chinese, Arabic, German, French, Russian, Italian, Vietnamese, Indonesian, Japanese, Korean, Spanish and Portuguese.
Who Benefits Most From This Supplier: Ceramic tile manufacturers (body and glaze flux for porcelain and wall tile), sanitaryware producers (ultra-white vitreous china bodies where Fe₂O₃ determines whiteness), tableware and porcelain factories (bone china, hotelware and premium dinnerware), container and flat glass plants (nepheline syenite as an alumina source that lowers melting temperature and improves chemical durability), fibreglass producers, glaze and frit manufacturers, ceramic pigment and engobe formulators, refractory producers, paint and coating manufacturers using fine mineral fillers, plastics and rubber compounders needing low-iron functional fillers, abrasive and grinding media plants, and mineral trading houses and distributors supplying ceramic clusters in Southeast Asia, the Middle East, South Asia, Europe and Latin America.
Product names, models and specifications as published on https://www.ceramicminerals.com/ at the time this profile was compiled. Verify all specifications directly with the supplier before ordering.
Top grade nepheline powder from the company's own quarry — wet-processed with multi-stage magnetic separation for the lowest iron content in the range. Specified for ultra-white ceramic bodies and premium porcelain.
Mid-grade nepheline powder for general ceramic body and glaze duty where cost per tonne matters alongside whiteness.
Economy grade nepheline powder for industrial ceramic, glass and filler applications with less demanding iron limits.
Potassium feldspar grade SY101 — K₂O 9-15%, Na₂O 3%, Al₂O₃ 17-19%, Fe₂O₃ 0.1-0.15%. Flotation processed for consistent chemistry lot to lot.
Potassium feldspar grade TX101 within the same K₂O 9-15% / Na₂O 3% / Al₂O₃ 17-19% / Fe₂O₃ 0.1-0.15% specification band, offered as an alternative grade for body formulation.
Custom sodium feldspar at Na₂O 11%, Al₂O₃ 19.5% — a lower melting point flux for glazes, wall tiles and glass batches.
Selling points, quality control, certifications and service commitments stated by the supplier — the reasons given for buying here rather than from a competitor.
120M+ tonnes of verified reserves in one deposit, so chemistry stays consistent over years rather than shifting with each purchased lot.
Multi-stage magnetic separation reaches iron levels the company states dry-process producers cannot match from the same ore.
Large-scale output with ample stock, sized for container and bulk vessel offtake rather than trial quantities.
Capital committed to the wet-process lines rather than reselling third-party mineral.
Mining, processing and export sales sit in one company, removing the trading margin and the traceability gap.
Fast access to Tianjin, Qingdao and Lianyungang gives routing flexibility and freight leverage.
1,200 kg jumbo bags for bulk consumers and 50 kg bags for smaller ceramic works and distributors.
Assay documentation and physical samples issued before order, with a stated 24-hour response.
Both terms quoted, so buyers can control freight or hand it over.
English, Chinese, Arabic, German, French, Russian, Italian, Vietnamese, Indonesian, Japanese, Korean, Spanish and Portuguese — built for ceramic clusters outside the English-speaking market.
The questions and objections that come up most often when buyers evaluate this supplier and this product category.
Iron oxide is the main colouring contaminant in a fired ceramic body. At 0.08% Fe₂O₃ the body fires white enough for premium porcelain and sanitaryware. At higher iron levels the same recipe fires cream or grey, which either forces a glaze change or drops the product grade.
Dry processing crushes and classifies the ore mechanically. Wet processing adds multi-stage magnetic separation in suspension, which removes far more iron-bearing minerals. Ceramic Minerals states that its wet-process lines reach Fe₂O₃ as low as 0.08% from ore that dry processing cannot bring to the same level.
Three nepheline powder grades — GP20, K200 and K100 — run from premium to economy on iron content and whiteness. Two potassium feldspar grades, SY101 and TX101, sit in the K₂O 9-15% / Na₂O 3% / Al₂O₃ 17-19% / Fe₂O₃ 0.1-0.15% band. Custom sodium feldspar at Na₂O 11% and Al₂O₃ 19.5% is available for lower melting point requirements.
1,200 kg jumbo bags for bulk consumers or 50 kg bags for smaller works. The quarry sits 3 km from the expressway with access to Tianjin, Qingdao and Lianyungang ports, and both FOB and CIF terms are quoted worldwide.
Yes. Samples and COA are supplied, with a stated 24-hour response on enquiries. For a ceramic body formulator the COA is the decision document, so it should be requested before any commercial discussion.
Not directly. Nepheline syenite carries more alkali and less silica than feldspar, so it fluxes at a lower temperature and typically allows a firing-temperature reduction or a faster cycle. Any substitution needs a trial firing against your own body, which is why samples and assay data come first.
