Zeolite monoliths have been found to be useful for such applications as rotatory adsorbers for use as dehumidifiers and desiccant cooling processes [360] or in VOC treatment systems [379]. Alumina-coated silicon carbide monoliths have also been employed as supports for B-ZSM-5 membranes [380] providing a larger surface area per unit volume, compared to traditional membrane supports. With these membranes, the same authors have reported n/t-butane and Hj/t-butane separation selectivities of 35 and 77, respectively [119]. Also, SIL-1 membranes supported on stainless steel grids (Figure 11.30) have shown a good performance in the separation of /t-butane mixtures, with separation factors as high as 53 at 63°C [362].

A wide range of applications for hard, wear-resistant coatings of electroless nickel containing silicon carbide particles have been discussed by Weissenberger . The solution is basically for nickel-phosphorus coatings, but contains an addition of 5-15 g/1 silicon carbide. Hiibner and Ostermann have published a comparison between electroless nickel-silicon carbide, electrodeposited nickel-silicon carbide, and hard chromium engineering coatings. 

Fluidized-bed CVD was developed in the late 1950s for a specific application the coating of nuclear-fuel particles for high temperature gas-cooled reactors. PI The particles are uranium-thorium carbide coated with pyrolytic carbon and silicon carbide for the purpose of containing the products of nuclear fission. The carbon is obtained from the decomposition of propane (C3H8) or propylene...

Silicon Carbide. SiC has low thermal expansion, high hardness, and good resistance to oxidation. It is used extensively in the coating of graphite and carbon to impart wear and oxidation resistance. 

If the composite is left only partially densified, it can be used as a filter for high temperature filtering systems with high collection efficiency as required in direct coal-fired gas and steam turbines. Similar systems are considered for particulate filtering in diesel engines by a carbon foam or felt coated with silicon carbide by CVI.

Apart from the reactions described above for the formation of thin films of metals and compounds by the use of a solid source of the material, a very important industrial application of vapour phase transport involves the preparation of gas mixtures at room temperature which are then submitted to thermal decomposition in a high temperature furnace to produce a thin film at this temperature. Many of the molecular species and reactions which were considered earlier are used in this procedure, and so the conclusions which were drawn regarding choice and optimal performance apply again. For example, instead of using a solid source to prepare refractory compounds, as in the case of silicon carbide discussed above, a similar reaction has been used to prepare titanium boride coatings on silicon carbide and hafnium diboride coatings on carbon by means of a gaseous input to the deposition furnace (Choy and Derby, 1993) (Shinavski and Diefendorf, 1993).

Besides the chemical industry, silicon is used as a powder in the ceramics (qv) industry for the production of silicon carbide and silicon nitride parts (see Advanced CERAMICS). Silicon powder is also used as an explosive for defense applications and in the refractory industry for plasma spraying with other oxide mixtures (see Refractory coatings). 

DPFs are important aftertreatment devices, enabling significant reduction in the emissions of PM. Typically, the filters are made of cordierite or silicon carbide materials, and can be either coated with a catalyst or left uncoated. The exhaust stream is forced to flow from one channel of the filter to an adjacent channel (see Fig. 37) the PM is filtered out by the wall of the filter.
