Summary:PROBLEM TO BE SOLVED: To provide a simple conveying member and transfer method for a silicon melt requiring no heating equipment in the production of high purity silicon used as the raw material for a semiconductor element and a solar cell. SOLUTION: The conveying member for a silicon melt is composed of an angled or cylindrical member having an extremely reduced heat capacity. The periphery thereof is protected with an insulating material having an extremely reduced heat capacity, and the total of the heat capacities in the conveying member is controlled to ≤13,000(J/Kg). By using this conveying member, a silicon melt is conveyed at a flow rate of ≥50(Kg/min) and also at a flow velocity of ≥0.1(m/sec). COPYRIGHT: (C)2011,JPO&INPIT
