| Abstract: | Silica sol slurry with good technical property has been widely applied m mvestment casting field, however the non ideal suspension property of the slurry affects its application in practical manufacture.The mechanism of suspension property and the relationship of suspension property and viscosity of flow cup and coating thickness were analyzed. It has excellent effect using Na-bentonite in silica sol slurry to improve its suspension property. |
