Optimization of the sintered density of aluminum oxide compacts

摘要

Effects of sintering time, peak temperature, heating rate, and binder system on the sintered density of alumina compacts were modeled using statistical methods. The traditional polyvinyl alcohol/polyethylene glycol (PVA/PEG) binder system produced more spherical spray dried granules and higher sintered densities than systems including hydroxyethylcellulose and 20,000 molecular weight PEG.
