Hey all,
I Have a powder of CaCO3 which I want to solidify (Hope that the right term)
I don't expect it to be like a lime stone but rather like a cracker that I can hold.
So I tried mixing it with H2O (distilled) and oven-dry it (60c 24h) and I do get a cracker,
The thing is I'm not sure whether it's still only CaCO3 or maybe some reaction have changed it (or part of it).
I followed the previous discussion in PF of CaCO3 reaction with water (https://www.physicsforums.com/threads/reactions-of-calcium-carbonate.420445/) but I can't get what happen when you dry the whole thing and take the water out (does the HCO3 condense back to CO3 and connects with the calcium?)
Further more - I want to do the same with but add also CaHPO4 (1/20 the amount of CaCO3).
So if I'll mix them, add water and then dry it, will I get the same materials or any reaction is expected to happen?
Thanks a lot
Moshe
