Abstract Powder-binder separation during injection moulding causes defects such as cracking, warpage or anisotropic shrinkage during firing. In this paper, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) have been previously used to analyse powder distribution within the green body for metal injection moulding are used for ceramics. TGA and DSC are used to characterize the mass loss and heat of fusion of the binder system, silicon nitride feedstock and test-bars. TGA can measure the volume fraction of powder in green parts directly with 1.76 vol% difference from nominal volume fraction and variations up to 0.177 vol%. The DSC empirical model predicted volume fraction of powder in green parts with 1.76 vol% difference from nominal volume fraction and variations up to 1.710 vol%. Using rule of mixture, it over predicted volume fraction of powder in green parts by 6.78 vol% from nominal volume fraction and with variations up to 2.510 vol%.

使用热重分析和差示扫描量热法对陶瓷生坯粉末注射成型的粉末分布

摘要 注射成型过程中粉末-粘合剂分离会导致烧制过程中出现裂纹、翘曲或各向异性收缩等缺陷。在本文中，热重分析 (TGA) 和差示扫描量热法 (DSC) 先前已用于分析用于陶瓷的金属注射成型坯体内的粉末分布。TGA 和 DSC 用于表征粘合剂系统、氮化硅原料和测试棒的质量损失和熔化热。TGA 可以直接测量生坯中粉末的体积分数，与标称体积分数相差 1.76 vol%，变化高达 0.177 vol%。DSC 经验模型预测生坯中粉末的体积分数与标称体积分数相差 1.76 vol%，变化高达 1.710 vol%。使用混合法则，
