Changzhou Zhuoqun New Nanometer Materials Co., Ltd.

Changzhou Zhuoqun New Nanometer Materials Co., Ltd. is based in China and currently lists eight active products. The catalogue spans several industrial segments, including Paints & Coatings, Metal Powder, Metal Alloys, Industrial Chemicals, Steel and Chemicals & Allied Products. Products enumerated are Dysprosium Oxide (Dy2O3), Lanthanum Oxide, Dysprosium Oxide Nano Powder, Yttrium Oxide Alloy, Cerium Dioxide, Yttrium Oxide (Y2O3), Y2O3 steel and Nano Y2O3. The nano‑powder items and the Y2O3 steel are identified with HS code 2846.90, which falls under Chapter 28 for inorganic chemicals. The remaining compounds are listed without specific HS codes in the supplied data.

In the rare‑earth oxide market, typical grades are specified by purity levels such as 99.9 % for bulk oxides and 99.99 % or higher for nano‑powders used in high‑performance coatings. Particle size for nano powders is commonly expressed in nanometres, with commercial grades ranging from 20 nm to 100 nm and a surface area of 10 - 30 m² g⁻¹. Yttrium‑based alloys for steel applications are usually produced with 90 % Y2O3 purity, matching the specification noted for the Y2O3 steel product. Cerium dioxide used in polishing or catalyst formulations is often supplied in grades of 99.5 % purity with a grain size of 0.5 - 2 µm. These technical parameters are standard references that buyers compare when evaluating the supplier’s offerings.

Changzhou Zhuoqun’s catalogue includes eight distinct rare‑earth oxide and alloy products: Dy2O3, Lanthanum Oxide, Dy2O3 Nano Powder (HS 2846.90), Y2O3 Alloy (HS 2846.90), Cerium Dioxide, Y2O3, Y2O3 steel (HS 2846.90) and Nano Y2O3. In the global market, Dy2O3 and Y2O3 are widely used as colorants and phosphor precursors in paints, coatings and electronic displays, with nano‑grade powders preferred for uniform film formation. Lanthanum Oxide and Cerium Dioxide are common in catalyst formulations and glass polishing, typically supplied in purity grades of 99.5 % to 99.99 %. Metal alloy variants such as Y2O3 steel are incorporated into specialty steel grades to improve grain refinement and high‑temperature stability. Buyers often request material safety data sheets (MSDS), particle size distribution, and purity certificates for these compounds.

Industry standards for these compounds include ISO 9001 quality management for production, while specific purity verification follows ASTM B717 for rare‑earth oxides. Nano‑powders are frequently tested against BET surface area methods and laser diffraction for particle size, and compliance with REACH registration is a common requirement for exports from China.
