High-temperature and high-vacuum annealing furnace

Abstract

The invention relates to vacuum coating experimental equipment, in particular to a high-temperature and high-vacuum annealing furnace. The furnace is characterized in that an ion pump, an annealing chamber cavity, a sample introduction chamber cavity and a molecular pump are sequentially connected, and the molecular pump is connected with a mechanical pump through a pipeline; gate valves are arranged between the ion pump and the annealing chamber cavity, between the annealing chamber cavity and the sample introduction chamber cavity and between the sample introduction chamber cavity and the molecular pump; and a fixed upper heater and a lower heater capable of lifting up and down are arranged in the annealing chamber cavity, a multi-layer sample library capable of lifting up and down is arranged in the sample introduction chamber cavity, and a manual transfer rod manipulator is mounted at one side of the sample introduction chamber cavity. Sample exchange with an annealing chamber can be rapidly completed through the high-temperature and high-vacuum annealing furnace under the vacuum condition, and it is guaranteed that the annealing chamber is in a high-vacuum state all the time. According to the high-temperature and high-vacuum annealing furnace, the cold-state limit vacuum degree of the annealing chamber can reach 10<-8> Pa ultrahigh vacuum, the hot-state vacuum degree can reach 10<-6> Pa when the annealing chamber is heated to 1600 DEG C, and long-time heat preservation annealing of a sample at the temperature not higher than 1600 DEG C can be achieved.

Description

technical field [0001] The invention relates to vacuum coating experimental equipment, in particular to a high-temperature and high-vacuum annealing furnace.
