研究了各种陶瓷材料对铅锂合金的热力学稳定性(Rg)随温度、锂组分和非金属溶质浓度的变化关系。对于非金属饱和合金，升高温度和降低锂成分(从锂到铅-17Li)都会导致稳定性增加(ΔRg值更正)。冷捕集降低锂中非金属溶质浓度会导致稳定性降低。在目前被评估为涂层材料的陶瓷中，AlN、TiN、TiC、Y2O和CaO在反应堆级的铅17Li中稳定，反应堆级的锂、β-碳化硅、氧化铝、二氧化硅和氧化镁在铅17Li中稳定，但锂和铬不稳定。
The thermodynamic stabilities (ΔrG) of various ceramics towards PbLi alloys have been evaluated as a function of temperature, lithium composition and, for lithium, non-metal solute concentration. For non-metal saturated alloys, both increasing temperature and decreasing lithium composition (from lithium to Pb-17Li) lead to increased stability (more positive ΔrG values). Reducing non-metal solute concentration in lithium by cold trapping leads to decreased stability. Of the ceramics presently being assessed as coating materials, AlN, TiN, TiC, Y2O3and CaO are stable in reactor grade Pb17Li and reactor grade lithium, β-SiC, Al2O3, SiO2and MgO are stable in Pb17Li but not lithium and Cr2O3is unstable in both breeders.
