Abstract

The invention discloses a simple single crystal furnace and a control method thereof. The simple single crystal furnace comprises a vertical tube furnace and a movement control system, wherein the vertical tube furnace comprises heating components, quartz taper tubes, quartz supports and a vacuum pump; holes for accommodating the quartz taper tubes are formed in the quartz supports, the quartz taper tubes penetrate through the holes in the quartz supports, the vacuum pump is connected with a flange at one end of a furnace tube, and a flange at the other end is connected with other protective gases (containing argon, nitrogen and the like), so that the inside environment of the furnace tube keeps an inert environment (in necessity) and the outside environments of the quartz taper tubes keep the inert environment (in necessity). The provided simple single crystal furnace is low in manufacture cost, occupies a small land area and is simple to operate. The single crystal growth principle is the Bridgeman method. Multiple kinds of large single crystals have been produced by means of the simple single crystal furnace, and the simple single crystal furnace has the effect equivalent to or even superior to the growth effect of a professional single crystal furnace.

Description

technical field [0001] The invention belongs to the technical field of single crystal growth, and in particular relates to a simple single crystal furnace and a control method thereof. Background technique [0002] At present, the single crystal furnaces on the market are expensive and complex, and are especially not suitable for the development of large single crystals in the laboratory. [0003] At present, the single crystal furnaces for growing bulk single crystals on the market are mostly the upward pulling method, and seed crystals need to be used before the growth of large single crystals. The operation is relatively complicated, and the equipment price is mostly more than one million yuan. This single crystal furnace uses the crucible descending method to grow single crystals, without the need for crystal seeds, and automatically forms crystal seeds. The growth process does not require any manual operation, the operation is simple, and the price is low. equipment. ...
