Abstract
A heat transmission apparatus is formed between a thermal source (12) and an object (21) in a vacuum enclosure (1) by placing in a cavity defined by a heat emission wall (20) and the object (21), a granular material (30) which adapts to the thermal expansions, while permitting heating by conductivity under very good conditions. Possible application to the manufacture of semiconductors and the crystallization of thin films.
