Kela Material presents Cerium Orange - One of the Cerium-Based Inorganic Pigment Series The main component of Kela cerium-based inorganic pigments is cerium sulfide. Cerium sulfide (Ce₂S₃) has a chemical composition approximating Ce₂S₃ and forms orthorhombic crystals. It is insoluble in water and strong alkaline solutions but readily dissolves in acids, releasing hydrogen sulfide gas. Under inert gas and reducing atmospheres, it maintains chemical stability up to 1500°C, while in oxidizing atmospheres it remains stable up to 350°C. Color Range and Properties The Kela Cerium Red cerium-based inorganic pigment series covers a color spectrum from deep red to orange-yellow. Cerium Red is a soft crystalline phase material that does not damage the structure of glass fibers in plastics and can actually enhance the mechanical properties of glass fibers. Key Advantages Non-toxic: Safe for use and complies with EU export standards and related national safety, health, and environmental regulations Strong covering power: Excellent opacity and color strength Good thermal stability: Maintains performance at high temperatures Environmentally friendly: Serves as an excellent substitute for toxic cadmium sulfide-based or heavy metal-based inorganic pigments Applications As a new type of green, environmentally friendly pigment, Cerium Red's high temperature resistance makes it widely applicable in: Plastics industry Rubber industry Other applications requiring heat-resistant, non-toxic colorants This innovative pigment represents a significant advancement in replacing traditional toxic heavy metal pigments while maintaining superior performance characteristics and meeting stringent international safety standards.

Kela Materials presents Calcium Copper Titanate (CCTO) — a leading high-permittivity ceramic material widely used in advanced capacitors and energy-storage components. CCTO is known for its extremely high dielectric constant, enabling large energy storage capacity. It maintains strong dielectric stability (ε’ ≈ 10⁶–10³) across a wide temperature range (100–600 K). When cooled to 100 K, the dielectric constant decreases sharply (ε’ ≈ 100), which is essential for evaluating temperature-dependent performance. CCTO’s combination of giant permittivity, stable dielectric behaviour, wide operating temperature range, and excellent processability makes it one of the best ceramic materials for next-generation high-energy capacitors and miniaturised components.
