Urea → Strontium carbonate

Participants

Reaction Steps

As shown in FIG. 1, a strontium nitrate (Sr(NO3)2) solution as a metal ion source was mixed in a container with a urea ((NH2)2CO) aqueous solution as a carbonate ion source to prepare a mixture solution containing 0.33M strontium nitrate and 0.33M urea. The container having the mixture solution was then placed into a reaction vessel and held at 90° C. for 90 minutes while agitating the mixture, whereby thermal decomposition of urea occurred to produce strontium carbonate crystals as the foregoing carbonate. The agitation was conducted at 500 rpm.
