HELLO everyone.. i have read some journals and some researchers (not all but most of them) said that bismuth manganate MUST be synthesized in high pressure conditions. in other words, not in room temperature/pressure. it that true? because some of researchers also synthesized that BiMnO3 in normal pressure (i just assumed it as normal pressure@not high pressure because they are not mentioned it in their journals) and use a solgel or solid state rxn method in their BiMnO3 researchs. which one is ok?
