TL;DR: In this article, LiMo2O4(OPri)5 (iPrOH) and iPrOH-3 (La(OPRI)3) were combined with water solutions in isopropanol, leading to the formation of monolythic gels, which can be converted by drying and heat treatment at 600°C into a fine powder of pure α-LiLaMo 2O8 phase.
Abstract: The hydrolysis of solutions, containing either LiMo2O4(OPri)5 (iPrOH) and “La(OPri)3” or LiOPri and La2Mo4O8(OPri)14 in 1 : 1 ratio, in toluene ori PrOH, by water solutions in isopropanol, leads to formation of monolythic gels. The latter can be converted by drying and heat treatment at 600°C into a fine powder of pure α -LiLaMo2O8 phase, which is transformed into β -LiLaMo2O8 powder by annealing at 800°C. The sintering of the pellets pressed under 4 bar pressure of α -LiLaMo2O8 powder at 800°C for 2 h converts them into pieces of β-LiLaMo2O8 transparent ceramics, thus providing a route to LiLnMo2O8 laser waveguide materials.
