Abstract

In work process of pressing of powder silicon is considered. By experimental way dependence of relative density on pressure of pressing a fine-grained powder and a coarse-grained powder are defined. Temperature dependence of consolidation at sintering of powders Ni, WC, ZnC, AlNi and Si is shown. Dependence of specific resistance of the poly-Si wafers and factor of self-diffusion on heat treatment temperature. Quantitative results of the analysis of a chemical compound of a surface of grains and micro pictures of two kinds of the poly-Si are resulted.

Keywords:Powder silicon; Polycrystalline; Pressing; Solar cells; Sintering; Substrate
