METHOD OF MELTING ALLOY CONTAINING HIGH-VAPOR-PRESSURE METAL

Title:

METHOD OF MELTING ALLOY CONTAINING HIGH-VAPOR-PRESSURE METAL

Document Type and Number:

WIPO Patent Application WO/2006/093334

Kind Code:

A1

Abstract:

A method of producing an alloy containing a metal which has a low melting point, low boiling point, and high vapor pressure, such as, e.g., magnesium, calcium, lithium, zinc, manganese, or strontium, through melting, wherein a helium-containing gas as an atmospheric gas is used for the melting. As a result, an alloy containing such metal and having a target chemical composition can be safely and inexpensively produced with satisfactory precision while preventing the problem that fine particles of a vaporized active metal incur a danger, e.g., ignition, or cause pollution. Furthermore, use of the helium-containing gas as an atmospheric gas enables the molten metal to be rapidly cooled and solidified due to the high thermal conductivity of helium gas. A special alloy can hence be produced even with an ordinary melting apparatus.
