Import Cobalt Oxide — Buy in Bulk from Supplier in China

Zhejiang Yuguang Aluminum Co., Ltd. supplies cobalt oxide powder with a melting point of 1935 °C. The material is insoluble in water, alcohol and ammonia water, but dissolves in acid and hydrate solutions. Chemical analysis reports cobalt at 72.1 wt% together with trace impurities of Zn 0.006 %, Fe 0.005 %, Ni 0.005 %, Cu 0.005 %, Mn 0.0015 %, As 0.002 %, Mg 0.002 %, Pb 0.005 % and Al 0.0059 %. Particle size is -325 mesh (≤44 µm) and each batch is packed in a 25 kg iron barrel with an inner plastic bag.

Typical cobalt oxide used for battery cathodes is specified at 99 % purity or higher and particle sizes between 1 and 10 µm. The supplied grade, with 72.1 % cobalt and -325 mesh size, is more suited to ceramic glazes and colour frits where lower purity is acceptable. Industry standards usually limit most metal impurities to below 0.1 % for such applications, matching the low impurity levels listed. Standard storage practice recommends a dry, well‑ventilated environment to avoid moisture‑induced colour shifts.

Buyers such as lithium‑ion battery manufacturers, ceramic glaze producers and pigment formulators may source this material in bulk. The 25 kg barrel with inner plastic bag eases handling for industrial shipments. Since the listing does not disclose MOQ, lead time or payment terms, importers should request these details directly from the supplier.

Zhejiang Yuguang Aluminum Co., Ltd. is located at 22# Hehua Road, Economic and Development Zone, Wuyi, Zhejiang, China (postal code 321200).
