The PBMR uses particles of enriched uranium dioxide coated with silicon carbide and pyrolytic carbon. The particles are encased in graphite to form a fuel sphere or pebble about the size of a billiard ball. The core of the reactor contains approximately 360 000 of
Hexoloy silicon carbide is produced by pressure-less sintering ultra-pure sub-micron powder and results in a pure alpha phase, finegrain silicon carbide product with virtually no porosity. The material retains useful strength up to 1650?C. Saint-Gobain have successfully manufactured 600 mm long tubes with an OD of 2.0mm and wall thickness down to 0.35mm, Figure 12.
Figure 2. Silicon carbide mechanical seal face damaged by electro-corrosion Ultra-Pure Water The scaling concerns addressed in the previous section are a particular concern in industrial boiler and cooling tower systems. To address this issue, improve reliability
Convective heat transfer coefficient of water, Cu-water, Al-water, Al 2O 3-water and TiO 2-water of 2 nanoparticle concentration has been calculated for counter flow heat exchanger. It is found that convective heat transfer coefficient of Cu-water, Al-water, Al 2O 3-water and TiO 2-water nanofluids are 81, 63, 66 and 64 higher compared to pure water respectively.

Heat pipe eedded aluminum silicon carbide (AlSiC) plates are innovative heat spreaders that provide high thermal conductivity and low coefficient of thermal expansion (CTE). Since heat pipes are two phase devices, they demonstrate effective thermal conductivities ranging between 10,000 and 200,000 W/m-K, depending on the heat pipe length.

Silicon carbide (SiC) porous substrates are prepared by pressureless sintering of SiC powders under an inert atmosphere of argon. The porous SiC substrates were characterized by measuring their porosity, pore size distribution, surface characteristics, and structure. Their transport characteristics were investigated using N2 and He as the test gases. Three different starting powders and four
Silicon carbide hex-reactor A first prototype of heat-exchanger reactor made of ceramic (SiC) has been developed in the frame of a collaboration between Boostec and LGC 7 (figure 2). Boostec is an innovative SME, specialized in high-performance all-silicon
Also, Silicon Carbide can also be used for exchangers as per requirement. Shell & Tube Heat Exchanger have a cylindrical shell which utilizes a glass tube bundle. All the tubes are fitted in the tube sheet. There is a sealing of PTFE ''O'' ring in each tube at both
