Strontium carbonate srco3 is the carbonate salt of strontium that has the appearance of a white or grey powder. it occurs in nature as the mineral strontianite. strontium carbonate is a white, odorless, tasteless powder.
Strontium carbonate is the carbonate salt of strontium. it is a tasteless and odorless white or grey powder. being a carbonate, it is a weak base and therefore is reactive with acids. it is otherwise stable and safe to work with. it is practically insoluble in water and occurs in nature as the mineral strontianite.
The kinetics of the solidstate reaction of strontium carbonate with anatase and rutile in air and carbon dioxide were studied by use of a thermobalance. the product was singlephase srtio 3 in all cases. the relation between fraction reacted and time was fitted to the jander equation and to the carter equation for both anatase and rutile.
