原始语种摘要: This project investigates the effect of polymeric binders and internal lubricant on mechanical properties and microstructure of sintered alumina. Three different formulations of alumina-binders were used which contained 3 wt% of Polyethylene Glycol (PEG) and various amount of polyvinyl alcohol (PVA) from 1 wt% to 3 wt%. About 3 wt% of stearic acid was used as an internal lubricant. Spray dry is the method that used to coat alumina powder with binders. Thermogravimetry analysis (TGA) was applied to determine the decomposition temperature of binders in the alumina-binder samples. Diametral compressive test was conducted to determine the tensile strength meanwhile the microstructure of fracture surface of sintered alumina was characterized by means of Scanning Electron Microscope (SEM). The...
