Strength and fracture toughness of barium titanate ceramics

Effect of processing variables on mechanical and electrical properties of Ho-doped BaTiO sub 3 with PTCR is studied. Diametric compression and four-point bending are used to measure strength. K sub / Ic / is evaluated using two methods: failure of SENB under four-point loading and cracking from a su...

Description
Summary:Effect of processing variables on mechanical and electrical properties of Ho-doped BaTiO sub 3 with PTCR is studied. Diametric compression and four-point bending are used to measure strength. K sub / Ic / is evaluated using two methods: failure of SENB under four-point loading and cracking from a surface indentation with diamond pyramid indentor.
