Zinc Ferric Oxide — HT Grade pigment optimized for high-temperature processing
High Temperature Iron Oxide Yellow also called Zinc Ferric Oxide Yellow, it is a reddish yellow which was produced after calcinated aboe 800℃. It has excellent heat resistance, light resistance, acid resistance and alkali resistance in common. As a result of our own advanced manufacturing technique and strict control, which endow it with high tinting strength and good dispersibility. This product is especial suitable for grass fiber masterbatch.
Our High Temperature Iron Oxide Yellow (zinc ferric oxide) is designed for demanding industrial applications where color retention at elevated temperatures is essential.
Typical uses include ceramic glazes, porcelain enamel, industrial coatings for ovens/furnaces, high-temp plastics, and refractory colorants.

Note: The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.
Unlike standard iron oxide pigments, our zinc ferric oxide HT grade incorporates zinc to enhance thermal resilience and reduce chemical migration during high-temperature processing. This results in more consistent color after firing and improved compatibility with ceramic and enamel matrices.
Yes—we offer custom D50 targets and pre-dispersed pastes optimized for specific binder systems. Tell us your application (firing temperature, substrate, binder) and we’ll recommend the best dispersion form.
Safety and compliance depend on final formulation and firing conditions. We can provide test reports and guidance; for food contact or exterior exposure, we recommend specific glaze recipes and firing profiles which we can help validate.
Standard packaging includes 25 kg paper drums and 500 kg bulk flexible containers. Small sample packs and pilot-scale orders are available. MOQ depends on region and shipping—contact sales for exact terms.
Dispersion depends on your binder and solvent system. Typical routes: high-shear milling for aqueous ceramic slips, solvent-based milling for enamels, or masterbatching for thermoplastics. We provide dispersion guides in the TDS.
