Microstructure and Mechanical Properties of Microwave Sintered ZrO2 Bioceramics with TiO2 Addition
The microwave sintered zirconia ceramics with 0, 1, 3, and 5 wt% TiO2 addition at a low sintering temperature of 1300°C and a short holding time of 1 hour were investigated. Effect of contents of TiO2 addition on microstructure and mechanical properties of microwave sintered zirconia bioceramics was reported. In the sintered samples, the main phase is monoclinic zirconia (m-ZrO2) phase and mino...
متن کاملMicrowave-Assisted Sintering of Al–ZrO2 Nano-Composites
Abstract In this project, nano-ZrO2 particles were dispersed in aluminum powder by a Y-shape mixer. The particle size of ZrO2 powder was < 40 nm and the amount of ZrO2 reinforcement varies from 3 to 15%.The mixed powders were compacted .Subsequently the compacted discs were sintered both in the microwave oven and in the conventional muffle furnace .Using microwave –assisted sintering method led...
متن کاملMicrostructure and mechanical properties of pressureless sintered alumina-silver composites
The silver toughened alumina ceramics, which were fabricated via a conventional ceramic processing route using commercially available alumina and silver oxide powders as the starting materials, exhibit a higher fracture toughness (6 to 9 MPamo.5) than the monolithic alumina ceramic ( 2.5 to 3.0 MPamo.5). The weak interfacial bonding between the silver inclusions and the alumina matrix is charac...
متن کاملMicrostructure and electrical properties of microwave-sintered PTC thermistors.
BaTiO3-based positive temperature coefficient (PTC) thermistors have been prepared by microwave sintering. The sintering process was carried out in a 2.45 GHz multimode microwave tube furnace without any susceptor The heating behavior of the PTC material, influence of processing conditions on microstructure, and electrical properties of the sintered samples were investigated. The sintering temp...
متن کاملSpark Plasma Sintered Hydroxyapatite – Zirconia Composites: Structural and Mechanical Properties
Hydroxyapatite (Ca10(PO4)6(OH)2) (HAp) is a very attractive material for human tissue implantation, beacuse it makes up ~69% of the weight of bone [1]. Unfortunately HAp posses low mechanical properties (strength, fracture toughness), which is a barrier to its applications in load-bearing situations [2]. The mechanical properties of HAp composites, is based on the synthesis of composites and th...
