Microwave Sintering of Thermistor Ceramics
Microwave sintering is a new sintering technology developed in the middle to late period of the 1980’s, which is characterized by fast densification for ceramic materials[1]. In recent years, microwave heating has been well employed in the field of sintering and joining of ceramics as a result of its advantages against conventional methods. These ceramic materials include oxides, mixed oxides, ...
متن کاملEffect of Thermal and Mechanical Aging on Flexural Strength of Zirkonzahn and Mamut Zirconia Ceramics
Objective: Despite the high strength of zirconia restorations, aging in the oral environment and masticatory loading may result in transformation of tetragonal to monoclinic phase and decrease their strength. Statements in this regard are controversial. This study sought to compare the flexural strength (FS) of Zirkonzahn (ZirkonZahn, Cercon, Ceramill) and Mamut (Dubai Medical Equipment LLC, ...
متن کاملEffects of the sintering conditions of dental zirconia ceramics on the grain size and translucency
PURPOSE This study aimed to identify the effects of the sintering conditions of dental zirconia on the grain size and translucency. MATERIALS AND METHODS Ten specimens of each of two commercial brands of zirconia (Lava and KaVo) were made and sintered under five different conditions. Microwave sintering (MS) and conventional sintering (CS) methods were used to fabricate zirconia specimens. Th...
متن کاملOn the Mechanism of Microwave Flash Sintering of Ceramics
The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.99 of the theoretical value in 0.5-5 min without isothermal...
متن کاملMicrowave Sintering of Ceramics for Dentistry: Part 2
Each tooth was then placed upon the reticulated zirconia in the thermal containment box and the technique of Microwave Hybrid Heating (MHH) was applied. The temperature measurements were taken every two minutes. We attempted to sinter the teeth in the microwave furnace with both fast and gradual heating rate (per minute) by manipulating the power rate. The power was increased gradually for few ...
