ollie1016 Posted April 18, 2013 Posted April 18, 2013 Hello All, I've been searching around and seen that Calcium Nitrate is cheaper than PotassiumNitrate. I was wondering if anyone has had any experience with it and could tell me a bit about it. I've searched google a bit and YouTube, but not really found a lot that's pyro related. I wouldn't be using it for my bp, but maybe as a oxidiser for some of my rockets. Any information would be great. Thanks
psyco_1322 Posted April 18, 2013 Posted April 18, 2013 Calcium nitrate is way too hygroscopic to use in pyro mixes.
AirCowPeacock Posted April 18, 2013 Posted April 18, 2013 Calcium nitrate is way too hygroscopic to use in pyro mixes. Practical pyrotechnics that is. You can still experiment with it, of course . . . ya know, for science. (;
pyrojig Posted April 19, 2013 Posted April 19, 2013 It can be a valuable oxidizer for chemistry as stated above. It can be used to create other hard to get nitrates by double decomposition .
pyrowinner Posted April 19, 2013 Posted April 19, 2013 (edited) As stated above Calcium nitrate [Ca(NO3)2] AKA: (Norwegian saltpeter) is the extremely hygroscopic, much more than Sodium nitrate. Because of that it's not used much in pyrotechnics. Edited April 19, 2013 by pyrowinner
pyrowinner Posted April 19, 2013 Posted April 19, 2013 (edited) But after all as pyrojig stated that 'it can be a valuable oxidizer for chemistry' Edited April 19, 2013 by pyrowinner
psyco_1322 Posted April 19, 2013 Posted April 19, 2013 yes, but its normally trihydrate. *tetrahydrate, Ca(NO3)2.4H2O
schroedinger Posted April 20, 2013 Posted April 20, 2013 If you can get it, mix it with the carbonat of the Nitrate you wan`t to get (Maybe you need to boil). Calciumcarbonate will precipate. Also sulfates work. You`re nitrate will stay in solution.Probably won`t work with Barium as these Salts are insoluble too
