The effect of acrylate on the properties and machinability of alumina ceramics

Effect of methyl methacrylate (MMA) as a binder and heating treatment were investigated to improve green alumina compacts machinability. Properties their corresponding sintered samples prepared with without MMA compared. Investigation properties was performed on compacted at applied pressures up 150 MPa. After pressing, thermally treated 115oC. The intention enhance the polymerization temperature little higher than glass transition (Tg = 103oC) poly (methyl methacrylate). Green had density values those MMA. Sintered lower total porosity; after sintering, relative linear shrinkage around 15 % for whole range pressures. possibility easily machining produces great possibilities application in many fields
