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.

MXene is a general term for complex atomic layer compounds composed of early transition metals (such as titanium, vanadium) and light elements (carbon or nitrogen), with a layered structure similar to graphene. The surface of the sheets has various polar functional groups, which gives them high dispersibility in hydrophilic materials.

Kela Materials develop a special grade Nano Zirconia (ZrO₂), a white powder ceramic material with a molecular weight of 123.22 and a very high melting point (around 2397 °C). It has high hardness, excellent wear resistance and chemical stability. At room temperature zirconia is an excellent electrical insulator, while at elevated temperatures it exhibits good ionic and electronic conductivity. Kela nano zirconia is engineered using a dual-crystal-phase (Magneli-type) structure to significantly improve dielectric strength and flexural strength. Compared with conventional zirconia powders, this material offers higher fracture toughness and better resistance to chipping and cracking, making it especially suitable for premium jewelry, high-end watch cases and bezels, as well as luxury 3C product housings and buttons.
