了解陶瓷粉浆的流变特性对于粉浆浇铸过程中的制备和控制都很重要。粉浆铸造广泛应用于白色陶瓷行业，因为它可以获得复杂的形状。陶瓷粉浆可以被认为是细颗粒悬浮液（粘土/高岭土悬浮液）中粗颗粒的悬浮液，其流变行为与粘土/高岭土悬浮液的流变行为密切相关。粘土/高岭土水悬浮液的剪切依赖性行为及其对各种因素（抗絮凝剂浓度、固体浓度、温度和分散过程持续时间）的依赖性已在之前的论文中进行了研究。”？在高固体浓度和低抗絮凝剂浓度下，粘土/高岭土悬浮液表现出触变行为很容易通过实验识别。
The knowledge of the rheological properties of ceramic slips is important for both preparation and control'purposes in the slip casting process. Slip casting is widely employed in the whiteware industries because it allows complex shapes to be obtained. A ceramic slip can be considered a suspension of coarse particles in a fine-particle suspension (clay/kaolin suspension) and its rheological behaviour is closely related to that of clay/kaolin suspensions.The shear-dependent behaviour of clay/kaolin aqueous suspensions and its dependence on a variety of factors (deflocculant concentration, solids concentration, temperature and duration ofthe dispersion process) have been examined in previous papers."? At high solids concentration and low deflocculant concentration, clay/kaolin suspensions exhibit a thixotropic behaviour which is easy to recognize experimentally.
