Lanthanum strontium manganite
Lanthanum strontium manganite (LSM or LSMO) is an oxide ceramic material with the general formula La1−xSrxMnO3, where x describes the doping level. In other words, the material consists of lanthanum manganite with some of the lanthanum atoms substitutionally doped with strontium atoms.

Weldon process
The waste manganese(II) chloride solution is treated with lime, steam and oxygen, producing calcium manganite(IV):
2 MnCl2 + 3 Ca(OH)2 + O2 → CaO·2MnO2 + 3 H2O + 2 CaCl2
The resulting calcium manganite can be reacted with HCl as in related processes:
CaO·2MnO2 + 10 HCl → CaCl2 + 2 MnCl2 + 2 Cl2 + 5
