The Effect of a Small Amount SiO2 on Sintering Kinetics of Tetragonal Zirconia Nanopowders
Abstract In the present paper the sintering behavior of 3 mol% yttria-stabilized zirconia (3Y-TZP) with and without small amount (0.2 wt %) of SiO2 additive was investigated. It has been studied the silica impact which was added in two ways (co-precipitation and mechanical mixing) on sintering kinet...
