Description of the process. The simplified process flow diagram is shown in Figure 16.12. The shredder waste (ASR, plastic and electronic waste as well as MSW) is fed in an IRFB, which operates in a reducing atmosphere and at temperatures as low as 500-600°C, allowing easy control of the process. The IRFB reactor separates the combustible portion and the dust from the inert and metallic particles of the fed waste the obtained mixture of metallic and inert particles is sent to a mechanical metal separation while fuel gas and carbonaceous particles are burnt in a cyclonic combustion chamber for energy production and fine ash vitrification. Metals such as aluminium, copper and iron can be recycled as valuable products from the bottom off-stream of the IRFB as they are neither oxidized nor sintered with...

Figure 7.1.16 shows a flow diagram of the process for synthesizing YAG sintered material using urea method powder as a raw material. This powder has a size of about 20 nm when fired. It is thought that secondary particles are formed... 

In the fabrication route used by Barringer and Bowen (89), powders with controlled characteristics are prepared and consolidated, by colloidal methods, into uniformly packed green bodies (e.g., similar to that shown in Fig. 1.17). An abbreviated flow diagram of the fabrication route is shown in Fig. 1.27b. Powders are prepared by controlled hydrolysis of titanium tetraisopropoxide (denoted powder I) or titanium tetraethoxide (powder II). The powder particles are nearly spherical and almost monosized. After washing, each powder is dispersed in a basic aqueous solution to produce a stable suspension. Consolidation of the suspension is accomplished by gravitational or centrifugal settling. The consolidated body is dried in a vacuum and sintered for —90 min at 800°C (for powder...

Figure 1 shows the schematic diagram of a water-nitrogen two-phase flow blowdown facility. The facility consists of the upstream tank, the test section and the downstream dump tank. The detail of the test section is shown in Fig. 2. The nitrogen-gas is supplied by a bomb, and it passes through a pressure regulator and a flowmeter and then blows out through a sintered metal ring on the head of the injector.

The Zr-Si phase diagram (Okamoto, 1990) indicates that Zr Sij forms liquid at the sintering temperature. Hence, it can flow into the microstructure filling voids among matrix grains favouring matter transport. When this phase gets in contact with a carbon source (Reaction 5), the formation of Zr Si and SiC is predicted from thermodynamical calculation ...
