High Heat Stable Red Oxide 101

Resilience at the Edge of Temperature

At Deqing Demi Pigment Technology Co., Ltd., we push the boundaries of mineral stability. We recognize that high-heat applications leave no room for error. Our high-heat 101 series is the result of advanced chemical engineering, providing a level of thermal insurance that standard pigments cannot match. We provide the "Heat-Proof" red that allows our clients to manufacture high-performance materials that maintain their visual identity even in the most extreme thermal conditions.

High-Heat 101 Usage Areas

• Engine Components: Heat-resistant coatings for blocks and manifolds.
• Plastic Masterbatch: For high-temp polymers like PEEK, PPS, and Fluoropolymers.
• Industrial Kilns: Coloring for refractory bricks and linings.
• Baking Enamels: Stable color for high-temperature industrial ovens.

Thermal 101 Technical Specs

Performance Features

• Absolute Shade Retention: No measurable ΔE shift under extreme heat stress.
• Low Thermal Expansion: Does not cause cracking in the host material at high temps.
• Chemical Resistance: Stable against molten salts and aggressive industrial gases.
• High Tinting Strength: Maintains opacity even at very low concentrations.

• Q: At what temperature does this pigment finally fail?

  A: Our high-heat 101 begins to melt only at 1565∘C; it is color-stable for most industrial uses up to 1000∘C.

• Q: Does the heat treatment affect the texture?

  A: No, the pigment remains a fine, easy-to-disperse powder that won't clump in your mix.

Extreme Condition Testing

We offer "High-Temp Isothermal Testing," where we bake your samples at your specific production temperature for 48 hours to guarantee performance.

Custom Surface Passivation: We can apply a nano-silica shell to the 101 particles to further protect them from chemical attack in molten glass or plastic.

The Science of Crystallographic Locking

The stability of our High-Heat 101 is achieved through "Lattice Consolidation." During synthesis, we use "Dopants" that sit within the crystal lattice and act as "Pillars," preventing the iron and oxygen atoms from migrating when energized by heat. This scientific "Locking" mechanism ensures that the crystal structure remains perfectly rigid. By preventing "Crystal Sintering" (where small particles fuse into larger ones), we ensure the surface area remains constant, which is the key to maintaining consistent color and opacity at extreme temperatures.
