I am trying to control the shape and morphology of barium oxide powders through co-precipitation method and a capping agent. I am limited in the choice of solvent (water) and the method (co-ppt). The general reaction yield is low owing to the high solubility of Ba(OH)2 in water. The only way I found to work is using alkali carbonate solutions. However, they afford rather poor control over the shape and size of precipitates.
Hence, I was wondering if someone has previously attempted to precipitate such compounds through high-temperature dissociation of urea in water. Any advice in this regard is highly appreciated.
Dear Aditya Chauhan please find attached a potentially useful article entitled "Synthesis and Characterization of Barium Oxide Nanoparticles" in which the use of BaCl2 and ammonia is reported. Also attached is an interesting paper describing "The mechanism of the decomposition of urea when heated in solution with alkalis and with acids respectively".
Dear Saleh Aljubouri please feel free to check out my RG thread entitled "What is spamming on this platform?" and provide your valuable answer:

Dear Prof. Frank T. Edelmann thank you for your valuable scientific insight. My project has made considerable progress since reading the suggested literature.
Would you be so kind as to provided your views on another topic that I find rather intriguing:
