Solid-Gas Reaction during Sintering of Si3N4 Ceramics. Part 6. Suppression of Mass Loss Reaction during Sintering.

Preparation of translucent YAG:Ce ceramics by reaction sintering

The paper presents preparation of YAG precursor powders mixture with ability for the reaction sintering at lower temperature. The powder mixture was mechanochemically processed and characterized for the specific surface area and crystallinity (XRD). Sintering experiments were performed on the batched powders, mechanochemically processed powders and as-synthesised YAG powders. XRD measurements a...

Solid Solution Formation during Liquid Phase Sintering

Sintering of Ceramics

Sintering with low frequency rf power (-50 M H z ) is a new technique with unique capabilities that has been used to sinter a variety of ceramic materials, including zirconia-toughened alumina, alumina, silicon carbide, and boron carbide. Processing with low frequencies offers many advantages compared to processing with conventional microwave frequencies (915 MHz and 2.45 GHz). Because of the l...

Direct Laser Sintering of Ceramics

For more than one decade layer manufacturing technologies assist the development of new products. Due to a layer-wise build-up of a three-dimensional geometry, nearly every complex design is producible in a short period of time. Selective Laser Sintering is a powderbased technique to produce plastic prototypes (Rapid Prototyping) or metal mould inserts (Rapid Tooling). The laser sintering of ce...

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, ...
