Metal-surface-treatment and battery-chemical projects should compare a defined cobalt-salt grade with their actual input requirements. TY-Cobalt Sulfate Heptahydrate is industrial CoSO4*7H2O, described as red-brown and easily soluble in water, with elemental cobalt content Co 21%.
Specify the surface-treatment or battery material duty
Identify the intended process and the chemical measurements required for acceptance. The listed uses do not establish coating quality or electrochemical performance, so a material enquiry should include the actual application criteria and relevant qualification evidence.
Confirm the content basis and individual impurities
Co 21% describes elemental cobalt rather than compound purity. Request current analysis for the offered heptahydrate model, including its reporting basis and the individual impurity measurements needed to compare the sample with the project’s grade limits.
- What does the pH report describe?
- The stated 3.5–5.5 applies to a 5% solution, not a surface-treatment bath or battery-process operating window.
- How should density be compared?
- The reported value is approximately 1.95g/cm³, with its actual method to confirm; it is not specified as bulk density.
Keep process qualification linked to the actual grade
Electroplating, catalyst and pigment/ceramic enquiries require their own relevant trials. Identity, cobalt content and a conditioned solution measurement should be considered alongside those results rather than substituted for them.
Store the material in a cool, dry place away from moisture as directed. Request current safety and technical information and appropriate sample evidence identifying TY-Cobalt Sulfate Heptahydrate. Acceptance should answer the chosen process and grade questions without an assumed finished-surface or battery result.
