Ceramic Grade Blue Oxide Pigment

Mastering the Art of Ceramic Blue

Deqing Demi Pigment Technology Co., Ltd. provides premium blue oxide solutions for the global ceramics industry. We understand that in porcelain and tile manufacturing, color stability under heat is the absolute priority. Our ceramic-grade blue is synthesized through high-temperature solid-state reaction to ensure a perfect crystalline lattice. We provide the "Cerulean Standard" that allows ceramicists and industrial tile producers to achieve breathtaking, consistent blues that last for centuries.

Ceramic Blue Usage Areas

• Porcelain Glazes: Deep blue coloring for high-fire tableware and art.
• Ceramic Tiles: Consistent blue for underglaze and overglaze applications.
• Sanitary Ware: Uniform blue tones for bathroom fixtures.
• Glass Enamels: High-opacity blue for decorative glass containers.

Ceramic Blue Technical Specs

Core Advantages

• Extreme Heat Stability: Will not fade or bleed during the firing process.
• Chemical Resistance: Stable against acidic or basic glazes and fluxes.
• Non-Migrating: Keeps sharp edges in decorative patterns during vitrification.
• UV-Permanent: Completely lightfast for exterior ceramic installations.

• Q: Can this blue be used for "Blue and White" porcelain?

  A: Yes, it is the modern standard for achieving traditional cobalt-blue effects with higher consistency.

• Q: Does it affect the glaze expansion?

  A: No, its low thermal expansion coefficient ensures it won't cause crazing or shivering in standard glaze recipes.

Ceramic Specialty Services

We offer "Kiln-Atmosphere Testing," providing you with sample chips fired at your specific temperature to ensure color accuracy.

Custom Micronization: We can provide ultra-fine blue oxides for screen-printing applications on delicate porcelain bodies.

The Science of Aluminate Spinels

The intense blue of this pigment is a result of Co2+ ions occupying "Tetrahedral Sites" within the Aluminate (Al2​O3​) crystal lattice. This scientific configuration creates a strong "Crystal Field" that absorbs red and green light, reflecting a pure blue. Because the cobalt is physically locked into the spinel structure, it cannot leach out or be altered by the aggressive melting of glass frits. This makes the CoAl2​O4​ structure one of the most stable and vibrant blue colorants known to material science.
