Indium Oxide In2O3 or Indium Trioxide In2O3 at Western Minmetals (SC) Corporation can be delivered with purity of 99.99%, 99.995%, 99.999% and 99.9999% 4N 4N5 5N 6N in size of 2-10 micron or -100 mesh powder and nano grade, 1kg packed in polyethylene bottle with sealed plastic bag, then carton box outside, or as customized specifications to the perfect solutions.
Indium Oxide In2O3 has a widespread use in photoelectric, gas sensor, thin film infra-red reflectors, catalyst application, specialty glass color additive, alkaline batteries, and high current electrical switches and contacts, protective coating of metallic mirror, and for semiconductor film of electro-optical display etc. In2O3 is the main constituent for ITO target for displays, energy efficient windows and photovoltaics. In addition, In2O3 is as a resistive element in ICs to form heterojunctions with materials like p-InP, n-GaAs, n-Si and other semiconductors. Meanwhile, Having surface effect, small size and macroscopic quantum tunneling effect, Nano In2O3 is primarily for optical and antistatic coatings, transparent conductive coatings application.
