Molybdates + photos

Hi. Today i made some metals molybdates. There are nickel copper and cobalt molybdates and THERE are manganese and some kind of gallium molybdate. I think it would be better if information on all types of molybdates were collected and not scattered at all points in the forum. I only have these molybdates at the moment, but I will definitely make others in the future.

Hi j_sum1 thanks for the offer, I also have that in the shed. The reason I'd rather use the molybdic acid MoO3 as a starting material is simply because I have some 500g of it.

Lion850 I just wonder where you bought 500g MoO3?

Vano there is a local chemical supplier that is happy to sell some stuff to hobbyists, and to let go of old stock cheap. The MoO3 came from him.

It is wonderful. Perhaps the seller knows the chemistry, I have a problem with the fact that most of them do not know the chemistry and just can not find the necessary compound. Chemicals that I have I have seen too many of them by chance, including sodium molybdate. If they knew chemistry I would have a lot of very rare substances today. But once more than half a kilo of Phosphotungstic acid was given to me because he did not know what to use it for, And many other substances as well.
