dangerousamateur Posted March 18, 2013 Share Posted March 18, 2013 Hi, can you give me a hint how much more calciumphosphate becomes soluble when I heat the solution? I just dissolved some perchlorate and since you mostly find 1,5g/100ml water, I put 3g perchlorate in 250ml cold destilled water. First I had a little white stuff on the ground, but after a little heating and stirring it disappeared completely. Now nothing remains - everything is in solution! I suspect there is some calciumphosphate in there, but I cannot find insoluble material. Link to comment Share on other sites More sharing options...

If potassium I don't believe there's any. If you mean ammonium, a very small amount of tricalcium phosphate is used as a free flow agent in MIL-SPEC material.

dangerousamateur Posted March 19, 2013 Author Share Posted March 19, 2013 Potassium Perchlorate. I thought there must be some anticake in there since it's very nice to handle. Sieve it once with a tea strainer and its airfloat. Now its about 15° Celsius again, still nothing at the bottom. Must be pretty good stuff then?
