Description

Produc

The specification for

99.8% pure cobalt varies depending on its intended application and physical form (e.g., powder, lumps, cathodes). However, standard-grade cobalt is defined by a minimum of 99.8% cobalt content, with specific limits on trace impurities.

General Chemical and Physical Properties

These properties are intrinsic to cobalt metal at this purity level.

Chemical Formula: Co
CAS Number: 7440-48-4
Purity: Minimum 99.8% (metals basis/trace metals basis)
Appearance: Grayish-white metal, often supplied as a black or grayish powder
Atomic Weight: 58.93 g/mol
Density: ~8.9 g/cm³ at 25 °C
Melting Point: ~1495 °C
Boiling Point: ~2900 °C
Magnetic Properties: Ferromagnetic

Typical Impurity Specifications

For industrial and commercial applications, maximum limits are placed on other elements. Below are examples of typical maximum impurity levels (weight %) for standard-grade or dissolving-grade coarse cobalt powder:

Element

	Maximum Limit (wt%)	Example Commercial Spec (wt%)
Nickel (Ni)	0.02%	0.095%
Carbon (C)	0.10%	0.0025%
Sulphur (S)	0.035%	0.0005%
Iron (Fe)	0.0035%	0.0004%
Copper (Cu)	0.0015%	0.00005%
Oxygen (O)	--	0.006%
Zinc (Zn)	0.0005%	0.0008%

Physical Form Specifications

The material's physical form dictates additional specifications, often used in applications like superalloys, batteries, and catalysts:

Form: Powder, spherical powder, lumps, cut cathodes, granules, or shot
Particle Size: Varies widely, e.g., 2 µm (microns), 28 nm (nanometers), or specific mesh sizes like -100+325 mesh
Bulk Density: Dependent on form; for nanopowder, it might be 0.10 - 0.25 g/cm³; for lumps, it is much higher
Safety/Transport: Often classified as a flammable solid (UN3089 or UN3288), especially in powder form.
