报道了La1−xSrxMnO3（x= 0,0.1, 0.2和0.3）的原位固体氧化反应。用过氧化锶、镧和氧化锰试剂制备了样品。过氧化锶诱导Mn+3氧化为Mn+4。得到了没有二次相形成的镧锶掺杂锰矿石。la0.825 sr0.175 mno3表现出了从88到373K和1073K的两次结构转变，低温下的Jahn-Teller效应和高温下的阳离子位移解释了这一转变。
In situ solid state oxidation reaction for an alternative La1−xSrxMnO3(x=0, 0.1, 0.2 and 0.3) formation is reported. Samples have been obtained by using strontium peroxide, lanthanum and manganese (III) oxide reagents. Strontium peroxide has induced the oxidation of Mn+3to Mn+4. Lanthanum strontium-doped manganite was obtained without secondary phase formation. La0.825Sr0.175MnO3showed two structural transitions, the first from 88 to 373K and the second at 1073K, which are explained by Jahn–Teller effect at low temperature and cation displacement at high temperature.
