Abstract

816,334. Crucibles. TELEFUNKEN G.m.b.H. Dec. 22, 1955 [Dec. 24, 1954], No. 36722/55. Class 82(1) A crucible particularly adapted for the melting of high-purity silicon consists of a quartz body 1 with an outer supporting jacket 3 of carbon which enables the silicon to be maintained at temperatures in the region of 1454‹C, the melting point of the quartz. The carbon is preferably in the form of graphite.
