Functional Oxide Series

Chromium oxide green possesses oxidation resistance, superior hardness, high wear resistance, and high temperature resistance.

VerdeChrome’s Functional Oxide Series features chromium oxide green (Cr₂O₃) as the core functional oxide. Boasting exceptional oxidation resistance, ultra-high hardness, high wear resistance, and heat resistance (withstanding over 1500°C), it delivers key value in industrial scenarios beyond pigments, ceramics, and glass.

Application of Refractory Materials

In refractory applications, VerdeChrome’s chromium oxide green (Cr₂O₃) serves as a critical additive in high-temperature equipment linings, including metallurgical furnaces and glass kilns. When blended with alumina and magnesia, it markedly boosts the thermal shock resistance and chemical stability of refractory bricks, castables, and coatings. This functional oxide maintains structural integrity even under extreme conditions—such as molten metal erosion or acidic flue gas corrosion—extending equipment service life by over 30%. Its applications span key industries: steel production, non-ferrous metal smelting, and waste incineration power generation, where it provides reliable protection for high-temperature furnace components against harsh operational stresses.
 

Application of Abrasive Tools and Abrasives

In the field of abrasives and grinding tools, VerdeChrome’s chromium oxide green (Cr₂O₃), with its ultra-high hardness (Mohs hardness 7-8) and excellent wear resistance, serves as a core functional component in high-performance grinding tools. When compounded with binders such as resin and ceramics, it can significantly enhance the grinding efficiency and durability of grinding wheels, grindstones, and other abrasive tools. In precision grinding scenarios, such as the polishing of metal bearings and optical lenses, chromium oxide green particles can reduce surface scratches on workpieces through uniform cutting action, bringing the surface roughness of the ground materials down to below Ra0.02μm, which meets the strict precision requirements of high-end manufacturing.

Energy Storage Application

In battery materials, VerdeChrome’s high-purity chromium oxide green (Cr₂O₃, purity ≥99%) serves as a critical dopant in cathode materials for lithium-ion batteries. Its unique crystal structure inhibits structural phase transitions during battery cycling, effectively preventing capacity degradation caused by repeated charge-discharge processes. This functional oxide extends the cycle life of ternary lithium batteries to over 2000 cycles, significantly outperforming conventional battery materials.
