Metasilicates


Hi today i made Ni and Cu metasilicates. I used chloride hexahydrate, sulfate pentahydrate and sodium metasilicate nonanhydrate. They have beautiful colours, i think i will make other metasilicates, Fe 2, Fe 3, Co and others.

First is nickel, second is copper.

Copper silicate look really nice. Try cobalt silicate, it have nice dark blue colour.

Thanks! Do you mean meta or orthosilicate?

I think that from aqueous silicate you always get mixture of silicates. Equilibria in aqueous silicate solution are quite complicated. Even your solid "metasilicate" isn't actually metasilicate, but polymeric species [Na2SiO3]x. There are ways how to produce some well defined silicates, like sodium orthosilicate or disilicate, but this isn't case of commercial stuff.

Yes i agree. But i saw photos where cobalt silicates have pink colour. To tell you truth, i don't like very much blue cobalt compound, but i love pink or red and such colours.

Cool! is there a difference in color if you create the anhydrous metal metasilicates (or orthosilicates) by dehydrating your samples or conversely, if your samples are anhydrous, can you hydrate them to see which new colors they'll exhibit?

Thanks. I think they are anhydrous salts, hydrates have more dark green and blue colour(They had such colors before I dried them and that is why I say). But I have seen copper metasilicate dihydrate having a light color on my metasilicate, probably because the powder is made up of much smaller particles.
