The elemental chemical composition showed a heightened weight content of calcium (Ca = 5.9%) in the samples, which promotes formation of anorthite, which increases the strength of articles, and a heightened weight content of carbon (C = 14.79%) attests the introduction of fuel into the green part body. The heightened weight content of fuel in the green body promotes uniform sintering of the ceramic inside the sample. A heightened weight content of iron (Fe = 2.98%) and alkali (R₂O = Na₂O + K₂O = 2.57%) in the sample will promote formation of a liquid phase at 950°C. X-ray phase analysis was confirmed by elemental analysis indicating that the heightened calcium content promotes the formation of anorthite.

元素化学成分显示样品中钙的重量含量增加（Ca = 5.9％），这促进了钙长石的形成，增加了制品的强度，碳的重量含量增加（C = 14.79％）证明了引入燃料注入绿色零件主体。生坯中燃料重量的增加会促进样品内部陶瓷的均匀烧结。样品中铁（Fe = 2.98％）和碱（R ₂ O = Na ₂ O + K ₂ O = 2.57％）的重量含量增加将促进在950°C形成液相。通过元素分析证实了X射线相分析，表明钙含量的增加促进了钙长石的形成。
