Materials of reduced thermal conductivity and of reduced proneness to sintering, based on the ZrO2 zirconium oxide, while these materials are modified with additives of rare earth oxides (the REO lanthanides) are basic directions in development of a new type of ceramic materials.
In a scope of interests, there are two types of materials from this group.

The optimum transesterification reaction conditions were gained as: n(propylene glycol monomethyl aether):n(carbonic acid dimethyl ester)=2:1, w(catalyst with a metal sodium) = 2% total amount of materials, reaction time 5h, and temperature keeping at 85℃.
Optimum condition were gained as: n(propylene glycol monomethyl aether):n(carbonic acid dimethyl ester)=2:1, w (catalyst with metal sodium)=2% total amount of materials, reaction time 5h, and temperature keeping at 85.
Conclusion Through orthogonal experiment, the optimum transesterification reaction conditions were gained as: n(propylene glycol monomethyl aether):n(carbonic acid dimethyl ester)=2:1, w(catalyst with a metal sodium) = 2% total amount of materials, reaction time 5h, and temperature keeping at 85℃.
