The raw materials used in the manufacture of ceramics range from relatively impure clay materials mined from natural deposits to ultrahigh purity powders prepared by chemical synthesis. Naturally occurring raw materials used to manufacture ceramics include silica, sand, quartz, flint, silicates, and aluminosilicates (e. g., clays and feldspar).
The invention provides an improved method and apparatus for feeding solids to a fluidized bed reactor. A back pressure control valve regulates the pressure drop between the pressure above a solids column in a standpipe and the pressure in the reactor. Solids are fed from the standpipe via a conduit without valve means, the conduit contains a bend of an angle greater than the angle of repose of ...
The new rotor tools are also available for laboratory mixers (from 1 liter). Particularly in the ceramic industry, it is often necessary to manufacture granulates with grain sizes ranging from 100 to 500 µm at laboratory scales. To date, only thermal methods have been available for doing this, such as fluidized beds or spray drying.
The silicon tetrachloride is converted with hydrogen into trichlorosilane in a conversion reactor. This process can be run homogeneously with hydrogen at approximately 1,000 °C in graphite reactors. We use the more elegant heterogeneous method of controlling the process by feeding silicon into a fluidizedbed .

The light material carried by the air flow exits out the top through the sifter channel and is conveyed via ducts to the cyclone where it is then separated and discharged through a rotary gate valve. In general, zigzag air separator systems operate in recirculation mode, where a ventilator blows the purified air back into the base of the ...
providing the raw material for silicon chips. Although glassmaking and foundry uses predominate, numerous minor uses are based on either the chemical purity or physical properties of the sand (such as grainsize distribution or grain shape). These include ceramics, water filtration, fluidizedbed furnaces and chemical manufacture. Owing to the
