METHOD FOR FABRICATING SI-AL ALLOY PACKAGING MATERIAL

摘要

PURPOSE: A method for fabricating a Si-Al alloy packaging material is provided to simplify production process, reduce production cost, and control Si content easily by mixing Si and Si-Al powder when producing the Si-Al alloy. CONSTITUTION: Si powder(13) and Al-Si compound power(14) are mixed to produce a compound powder with predetermined Si content, which should be controlled to range from 40 to 90 weight percentage. When Si and Si-Al powder are mixed, total Si content is calculated by adding the weight percentage of pure Si to that of Si in Si-Al compound powder. The mixed compound powder is press-formed while current is applied to it. Plasma arc occurs and packing material with Si content is produced.
