Cobalt nitrate hexahydrate
Description
Cobalt nitrate hexahydrate (CAS 10026-22-9), also known as cobaltous nitrate hexahydrate, is a water-soluble cobalt salt supplying bioavailable cobalt across agricultural, industrial, and specialty chemical applications.
It functions primarily as a cobalt source in catalyst preparation, micronutrient formulations, and surface treatment processes. In agriculture, it is incorporated into trace element fertilizers and animal feed supplements.
This product is used to correct cobalt deficiency in soils and livestock, particularly in ruminant nutrition programs. Catalyst manufacturers use it as a cobalt precursor in the production of hydroprocessing catalysts.
In Fischer-Tropsch catalysts, controlled cobalt loading is critical to performance. In the ceramics and pigment industries, it serves as a raw material for cobalt-based colorants applied to glass, glazes, and specialty coatings.
Pharmaceutical and nutraceutical formulators source it as a cobalt intermediate where precise metal content and low impurity profiles are required. Cobalt nitrate hexahydrate is supplied as red-pink crystalline granules or flakes.
Technical grade is the standard commercial form, with purity levels typically ranging from 98% to 99%+. Reagent and high-purity analytical grades are available for catalyst and pharmaceutical applications.
These specialized grades are designed for processes requiring tighter metal impurity specifications. The material ensures consistent performance across diverse industrial sectors and high-precision manufacturing environments.
