Polycrystalline silicon production in a fluidized bed. The fluidized bed reactor process is not without its challenges. With graphite reactors, heating is limited to the walls, which limits scale-up due to heat transfer challenges from the decreased surface to reactor volume ratio of larger units. Fines build-up in the freeboard region can also ...

The silicon carbide was deposited from methyltrichlorosilane (MTS), CH3SiC13, in a bed of microspheres fluidized with hydrogen. The coating rate, the morphology, the microstructure and the density were studied as functions of temperature in the range 1225-1775 and with concentrations of 2.4-16.7 vol. MTS in hydrogen (HZ : …

Stoichiometric silicon carbide coatings the same as those used in the formation of TRISO (TRistructural ISOtropic) fuel particles were produced by the decomposition of methyltrichlorosilane in hydrogen. Fluidized bed chemical vapor deposition at around 1500 °C, produced SiC with a Young's modulus of 362 to 399 GPa. …

Fluidized Bed Powder Coating for Racks, Baskets, Brackets & More. A fluidized bed is a container of PVC or nylon powder that has air blown into it from the bottom. This air makes the solid powder "fluidize" or act like a liquid. Piper Plastics typically fluidizes both PVC and Nylon powders in a multitude of colors, and we have some ...

The fluidized bed coating acts like a sort of dip painting, that is, the workpiece, preheated in an oven and, then, fed to a fluidization column and kept in a fixed position, is subjected to strikes from polymeric powders pushed all over the fluidization column by the fluid. Impinging onto the hot surface of the workpiece, the powder melts ...

The influence of nozzle position is examined during the fluidized bed coating of silica sand particles by NaCl solution [6]. The saline solution is introduced over the bed at three levels: 0.13, 0.23, and 0.33 m above the air distributor. Note that the 0.13-m level corresponds to the height of the fixed bed (H o). The results show that –

Post heat it for one-and-a-half min at 350°F. This will normally produce a film build between 10–12 mils. On applications such as bike racks, where 30 mils of coating are desired, heat the part for six min at 550°F, dip it for 30 seconds and post heat it for one-and-a-half min at 400°F.
DetailsThe Fluidized bed coating process as a developed pharmaceutical technique, is now strongly being applied in the food and pharmaceutical industry to tune the effect of functional ingredients, drugs, and additives (Hall and Pondel, 1980; Mehta et al., 1986).In this method, particles are introduced into the chamber and fluidized by air.

Fluidized-Bed Process for Producing Silicon from Silane. Fluidized-bed technology works well with silane as the feed gas to make silicon. The FB reaction involves the deposition of silicon from silane onto small, heated particles of silicon that are suspended in a flow of feed gas as shown in Fig. 1. Fig. 1.
