Abstract The hydrolysis of solutions, containing either LiMo2O4(OPr i )5( i PrOH) and “La(OPr i )3” or LiOPr i and La2Mo4O8(OPr i )14 in 1∶1 ratio, in toluene or i 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.
