- By adjusting the content of additives and changing heating conditions, the influential factors in leucite synthesis were explored. 采用固相反应法，通过调整添加剂的含量，制定不同的热处理制度探讨了白榴石合成中的影响因素。
- Research included leucite preparation and ceramic frit preparation matching leucite.Solid phase reaction was used to prepare leucite. 课题研究包括白榴石晶体的制备和与白榴石相匹配的烤瓷熔块的制备。
- Two ways were used to prepare PFM powders, one was to add different proportions of leucite to the ceramic frit, and the other was to grain-process the ceramic frit. 采用在烤瓷熔块中加入不同比例的白榴石和对烤瓷熔块进行晶化处理两种途径制备金属烤瓷粉。
- The conversion ratio of potassic feldspar to leucite in alkali trachyte is mainly controlled by temperature when it is less than1100℃ and by the cooling velocity of temperature when it is over1100℃. 富钾粗面岩中钾长石向白榴石的转化率在1100℃前主要受焙烧温度控制；在1100℃后则受其后的降温速度控制。
- This will causedifferent ascent velocities and then different diffusion rates of volatile in magma. The change of the pH2o in magmas during their ascenting triggers the changes of the stability of phlologopite,leucite and sanidine. 从而引起岩浆在上升过程中所含挥发分发生散失的程度有差异，造成PH2o的变化，而这正是控制金云母、透长石及白榴石稳定性及变化的主要物理参数。
