Hi everyone!!!
I need cobalt compounds & I read about one of them (cobalt aluminate) but I don't really know what is its uses (as a dye of course). I need your
help.

Where are you from? You could try extracting cobalt from old Alnico magnets, or from colored silica gel (the colorant is cobalt chloride) if you don't
have readily access to cobalt pigments.

LiCoO2 is the most common, though it is a very strong oxidizer and can be explosive under the wrong conditions. Reduce with care. Cobalt alloys
are also used as high-strength metals under the trademark "Stellite" or "Talonite", but extracting cobalt from the mixture is likely to be a pain.
Most cobalt pigments seem to have been replaced by manganese or aluminum or organic dyes, but cerulean blue (cobalt stannate) is still one of the most
popular ones out there, not surprising as it does look pretty awesome. Make sure you don't end up with copper phthalocyanine.

Yes LiCoO2 is the most common. It is found in lithium ion batteries and some in NiMH batteries.

I can't seem to find much sources on cobalt blue. I found some in a hobby pottery shop on the Internet and some cobalt blue paint but it's expensive.

Cobalt carbonate and cobalt sulfate are easy to find sources of cobalt salts, which can be purchased at ceramics and pottery shops. These chemicals
are affordable.
