Heat-stable iron oxide black for ceramics, refractory, high-temperature coatings and plastics.
High Temperature Iron Oxide Black is a thermally stable inorganic pigment designed for applications requiring deep black color after exposure to elevated temperatures. Optimized for ceramics, refractory coatings, enamels, and high-temperature plastics, it delivers consistent particle size distribution and excellent resistance to oxidation and fading.
High Temperature Iron Oxide Black also called Manganese Ferrite Black, 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. EMP-H has higher tinting strength.
Handle as an inorganic pigment. Use dust control and appropriate PPE (mask, gloves, goggles) during bulk handling. Product safety data sheet (SDS/MSDS) available upon request. Not for food, cosmetic, or medical use unless otherwise specified.
Lead time: Typically 2–4 weeks for bulk orders.

Yes — with proper formulation. Solid loading, dispersant selection and rheology modifiers should be optimized. We recommend laboratory trials and can provide small samples for testing.
For glazes, pre-wetting the pigment into a slurry and using high-shear mixing improves dispersion. Test small batches to optimize binder and dispersant levels for your specific glaze recipe.
Maximum firing temperature depends on the formulation and substrate. Typical applications retain stable color up to the range of 900–1000°C; consult the technical datasheet for exact recommendations based on your process.
