【摘要】 用熔盐溶液理论分析了液相结构对烧结过程中通过液相的传质过程的影响。认为除粘度及对固相的润湿等性能外,液相结构也是影响烧结的重要因素之一。只有当在烧结中生成的液相为接近于理想溶液的熔盐溶液时,液相的出现才有可能使通过液相的溶解-沉淀过程顺利进行。溶解能参数f(γ)可以被用来近似地判断液相结构对烧结的影响,只有当f(γ)的值接近于零时,液相的生成才有可能有利于通过液相的传质过程。更多还原

【Abstract】 The effects of the structure of liquid phase on material-transfer during sintering of cera-mic materials have been analysed in the light of theory of molten salt solution. Apart fromits viscosity and wettabilitly, the structure of liquid phase is one of the important factorswhich affects sintering. During sintering the solution-precipitation process may proceed fa-vorablty if the liquid phase existing is approximate to an ideal molten salt solution. Theenergetic parameter of solution, as an approximate lunction of electrostatic energy of mix-ing of molten salts, may serve as an approximate criterion for estimating the effects ofstructure of liquid phase on sintering of ceramic materials. The transfer of materialthrough solution may proceed only when f(r) approaches zero.更多还原
