Kela Materials presents Strontium Vanadate (SrVO₄), a new-generation transparent conductive material considered a promising alternative to indium tin oxide (ITO). ITO has dominated transparent conductive films for over 60 years, but indium prices continue to rise, making cost and supply increasingly challenging for display and semiconductor industries. SrVO₄ offers high visible-light transparency while providing good electrical conductivity and stability, making it a strong candidate for next-generation display materials, optoelectronic devices and transparent electronic components. Since 2015, multiple international research groups have identified SrVO₄-based systems as potential substitutes for ITO due to their lower cost, easier processing and excellent optical–electrical performance.

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.

SWCNT Slurry – High-Conductivity Single-Walled Carbon Nanotube Dispersion for ESD Plastics, Coatings and Battery Materials

SWCNT slurry is a high-conductivity, pre-dispersed formulation of single-walled carbon nanotubes. It provides fast, uniform dispersion in plastics, coatings and battery materials, enabling ultra-low loading, stable resistivity and clean processing in water, NMP or ethanol.

Introduction

Our SWCNT slurry is formulated using high-aspect-ratio single-walled carbon nanotubes (eDIPS process). Through proprietary dispersion technology, the CNT network remains stable and uniform in water, NMP, ethanol and mixed systems. It is designed for ESD plastics, conductive coatings, printed electronics and battery electrode additives.

Key Features

• Excellent dispersibility in water, NMP and ethanol
• Long-aspect-ratio SWCNTs preserved during dispersion
• 5–10× lower loading vs. carbon black for same resistivity
• Compatible with PC/ABS, PA, PBT, TPU, PU, epoxy and coatings
• Stable electrical performance and uniform percolation
• Available in multiple concentrations (0.05–0.4 wt%)

Applications

• ESD & antistatic plastics
• Conductive and shielding coatings
• Printed electronics and conductive inks
• Lithium-ion battery electrodes
• Transparent and semi-transparent conductive films

Product Grades

Grade	CNT Type	Solvent	Concentration
SWCNT-A	EC1.5-P	Water	0.1–0.4 wt%
SWCNT-B	EC2.0-P	NMP	0.05–0.3 wt%

Comparison vs Carbon Black
