摘要

Disclosed is a high temperature magnetic stirrer including a permanent magnet positioned underneath a frame supported platform. The magnet is positioned to be rotatable in a plane parallel to the platform. A spiral shaped heating element mounted to the frame is positioned above the platform and centered above the rotatable magnet. The spiral has a diameter sufficient to enclose a portion of a crucible.
