Modeling of silicon particle growth. Progress report

Description: Efforts at the Jet Propulsion Laboratory toward the production of pure polycrystaline silicon are centered on the concept of silicon particle growth in a fluidized bed reactor (FBR) and a continuous flow pyrolyzer (CFP). The CFP possibly can provide the seed particles which will be grown to larger sizes in the FBR. In both the reactors polycrystalline silicon is obtaned from the pyrolysis of silane. A part of the JPL effort is to develop a model of silicon particle growth for the purpose of pre… more

Purification of silicon by the silicon fluoride transport process. Thermochemical study

Description: A computer-assisted thermochemical equilibrium analysis was conducted for the silicon transport reaction: Si(s) + SiF/sub 4/(g) = (intermediates) = Si(s) + SiF/sub 4/(g). The calculations indicated that a substantial transport rate should be possible at temperatures of 1700/sup 0/K and one atmosphere pressure. Computations were made to determine whether the elemental impurities present in metallurgical-grade silicon would transfer in this process. It was concluded that aluminum, chromium, coppe… more

Normative price for a manufactured product: the SAMICS methodology. Volume II. Analysis. JPL publication 78-98. [Solar Array Manufacturing Industry Costing Standards]

Description: The Solar Array Manufacturing Industry Costing Standards (SAMICS) provide standard formats, data, assumptions, and procedures for determining the price a hypothetical solar array manufacturer would have to be able to obtain in the market to realize a specified after-tax rate of return on equity for a specified level of production. This document presents the methodology and its theoretical background. It is contended that the model is sufficiently general to be used in any production-line manufa… more
