Push-pull double-cavity transition high-temperature device

Abstract

The invention discloses a push-pull double-cavity transition high-temperature device. The device comprises a first gate valve, a quartz boat, a second gate valve, a transition cabin and a device frame, a first sliding rail is horizontally installed at one end of the top of the device frame, And the first sliding rail is connected with a right end flange through a sliding block. The transition cabin is additionally arranged between heating furnaces, and after a sample is placed in a quartz cavity through the quartz boat and is heated and reacted in one environment atmosphere, the sample entersa quartz cavity at the other end through the vacuum transition cabin and is heated and reacted in an another environment atmosphere, so the phenomenon that the material is heated in one environment atmosphere and then transferred to the other environment atmosphere to be exposed in the air to be oxidized is completely avoided in the process; and sample displacement of the quartz boat in the transferring process is avoided, the sample is stably transferred through the quartz boat in a quartz push rod push-pull mode, and a balance pipeline is additionally arranged between the flange and the transition cabin and used for balancing the pressure in the quartz cavities and the pressure in the transition cabin.

Description

technical field [0001] The invention relates to the technical field of push-pull double-cavity high-temperature transition, in particular to a push-pull double-cavity high-temperature transition equipment. Background technique [0002] Generally, when materials are grown in vacuum atmosphere tube furnace equipment, only one gas can pass through during the heating process, or multiple gases can pass through the gas mixing tank and then pass into the tube; that is, the experimental sample can only be heated and reacted in one atmosphere, and cannot be heated in a vacuum. In the state, the heating is converted from one ambient atmosphere state to another ambient atmosphere state; and the sample cannot be transferred from one quartz cavity to another quartz cavity by external force in a vacuum state; the vacuum atmosphere tube furnace is now It is a very commonly used and important experimental equipment for laboratories that require medium and high temperature conditions. When...

[0002] Generally, when materials are grown in vacuum atmosphere tube furnace equipment, only one gas can pass through during the heating process, or multiple gases can pass through the gas mixing tank and then pass into the tube; that is, the experimental sample can only be heated and reacted in one atmosphere, and cannot be heated in a vacuum. In the state, the heating is converted from one ambient atmosphere state to another ambient atmosphere state; and the sample cannot be transferred from one quartz cavity to another quartz cavity by external force in a vacuum state; the vacuum atmosphere tube furnace is now It is a very common and important experimental equipment for laboratories that require medium and high temperature conditions.

When the general atmosphere tube furnace equipment is heated up, the gas is introduced in a vacuum state, and the sample material can only react in one atmosphere. This method is very effective for general materials, but it cannot meet the requirements of special materials in one ambient atmosphere. Heating requirements for switching to another ambient atmosphere
