CONTROL METHOD AND APPARATUS |
摘要 |
The growth of a solid obtained by cooling a liquid solution is observed and controlled by measuring the variation in volume of the solid-liquid system at the time of solidification. The method is applicable to the control of oriented crystallization from an initial crystal seed or epitaxial growth on a substrate having a suitable crystal orientation. The rate of crystallization can be controlled by means of a furnace provided with means for producing regulated thermal gradients, temperature-measuring means, a chamber filled with an inert liquid, an open-topped container filled with the liquid to be solidified and immersed in the inert liquid, the container being suspended from one arm of the beam of an electrobalance. |
