Phase Formation, Microstructure and Mechanical Properties of ZrO2 Modified-Dental Porcelain Ceramics
ثبت نشده
چکیده
The potential of a combination between single-step sintering and ZrO2 additive as a simple ceramic fabrication method to obtain dental porcelain-based ceramic-nanocomposites with good mechanical properties was demonstrated. Influences of sintering condition on phase formation, densification, microstructure and mechanical properties of these porcelain ceramics were examined via XRD, SEM-EDX and Vickers indentation. It has been found that the choice of both sintering temperature and dwell time is one of the key factors controlling densification and leucite crystallization on the zirconia surface in dental porcelain ceramics.

Effects of a convenient silica-coating treatment on shear bond strengths of porcelain
Significant progress has been achieved in ceramics since the late 1990s1-4). In particular, new technological innovations such as heat-pressed5,6), injection-molded7), slip-cast8), and glass-infiltrated ceramics9-11) have widened the use of ceramics in prosthetic and operative dentistry. However, properties such as brittleness limit their use in applications such as fixed partial dentures. Sinc...

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...

Dental porcelain composites reinforced and toughened by 20 wt.% tetragonal zirconia (3Y-TZP) were processed by hot pressing at 1000°C. Two types of particles were tested: yttriastabilized zirconia (ZrO2–3%Y2O3) agglomerates and pre-sintered yttria-stabilized zirconia (ZrO2–3%Y2O3) particles. The composites as well as the reinforcing particles were analyzed by the means of optical and Scanning E...
متن کاملThe effect of fired scrap addition on the sintering behaviour of hard porcelain
The effect of the addition of porcelain fired scraps on the sintering, phase composition and properties of a hard porcelain was studied. Two ceramics were compared: a commercial triaxial porcelain labelled C-0 and one, where 15% of the mass of C-0 was substituted by scraps yielding a composition labelled C-15. The sintering was evaluated by the linear shrinkage, the water absorption and the var...

Synopsis The application of zirconia ceramics for the dental restorations and dental implants has increased. However the weak performance of the veneering porcelains and low adhesion to the zirconia framework were reported. In this study, the micro-structure, elemental distribution and crystal phase around the interface between zirconia and veneering porcelain were estimated using SEM-EDS (ener...
