Untitled edit
I would like to get my hands on some more information such as some of the properties and maby some other chemistry related uses. LoyalSoldier 09:10, 5 January 2007 (UTC)
Opening comments edit
Most of this was data I could find from sources I had on hand. If you find anything that might be helpful please do post the information.
Updated edit
I've made some additions as per the expansion request. You might want to check your sources more carefully, some of the info looked incorrect or misunderstood. 1.1.1 06:38, 13 January 2007 (UTC)
Some of them didn't look quite right which is why I put in a the request. At the time I only had minor sources because the chemistry reference did not cover some of the Strontium Salts. As for the use of Carbon Dioxide to form this compound I found that method on a government website.LoyalSoldier 00:30, 17 January 2007 (UTC)
- I have found the reaction I originally found. It seems that there is a method to get the Strontium into a Sr(HCO3)2 form and from there you can do an equilibrium reaction using Carbon Dioxide in order to force the reaction to form Strontium Carbonate. LoyalSoldier 20:47, 4 February 2007 (UTC)
Pictures forth coming edit
I am about to take possession of about a pound of Strontium Carbonate for my pyrotechnics. I will post the picture of it on the page here soon. LoyalSoldier 07:03, 14 February 2007 (UTC)
- Excellent. Consider posting pictures of it burning too - much prettier than just the white powder. Theresa Knott | Taste the Korn 23:00, 14 February 2007 (UTC)
- That is a good idea. I plan on using this for an acid neutralizer in a star since I am using sulfur. I will take a picture of it during ignition. BTW the picture of it is up.LoyalSoldier 23:02, 15 February 2007 (UTC)
Preparation from celestine edit
I see that strontium sulfate as listed as a raw material for making strontium carbonate, by reaction with a water-soluble carbonate. Surely that's not too practicable, bearing in mind the low solubility of SrSO4? Wouldn't the reaction have to be done under such dilute conditions so it's not worth it? Or is it reduced to the sulfide by roasting with carbon first? Walkerma 04:32, 15 February 2007 (UTC)
- No it is not made from solution chemistry. I may rewrite that to make it clear. Because Strontium occurs naturally in the Sulfate form it is easier to use a process to form Carbonates since they tend to be more useful than the sulfates. LoyalSoldier 22:37, 15 February 2007 (UTC)
Decomp at Melting not Boiling edit
I think someone must have typed it in the wrong box. I look up the MSDS at sciencelabs.com
http://www.sciencelab.com/xMSDS-Strontium_carbonate-9925106
It decomposes at the melting point. I also changed the MSDS as sciencelab's is much better. LoyalSoldier 23:17, 15 February 2007 (UTC)
Uses edit
The line "mixed with sulphur to make SrS:x where x is typically europium[citation needed]." seems to be incorrect as europium (Eu) gives a red light[1] and it is Cerium (Ce) that is associated with Blue/Green.[2]

Copyvio concern edit
I have commented-out several blocks of content that match [1], which itself appears fail WP:RS at best. Because archive.org is giving me an error at the moment, I cannot determine whether we had copied from them or instead they copied from us. When that heals, we need to look into the histories and either actually remove our infringing material or else tag as {{reverse copyvio}}. DMacks (talk) 14:25, 26 June 2019 (UTC)
