    Two-Step Sintering of Oxide Ceramics with Various Crystal Structures

  • Original language description

    The influence of Two-Step Sintering (TSS) process on the final microstructure of oxide ceramic materials with three different crystal structures was studied. Two kinds of alumina (particle size 100nm resp. 240nm) as well as tetragonal zirconia (stabilized with 3mol%Y2O3, particle size 60nm) and cubic zirconia (8mol%Y2O3, 140nm) powders were cold isostatically pressed and pressureless sintered with different heating schedules. The microstructures achieved with TSS method were compared with microstructures achieved with conventional Single-Step Sintering schedule (SSS). The results showed that the efficiency of the TSS of these oxide ceramics was more dependent on their crystal structure than on their particle size and green body microstructure. The method of TSS brought only negligible improvement of the microstructure of tetragonal zirconia and hexagonal alumina ceramics. On the other hand, TSS was successful in the sintering of cubic zirconia ceramics; it led to a decrease in grain si
