Embodiment Construction

[0022] Implementation example

[0023] 1. Prepare the precursor solution. Mn for the target component 1.56 co 0.96 Ni 0.48 o 4 Manganese oxide, respectively weigh 91.76g of manganese acetate tetrahydrate, 57.39g of cobalt acetate tetrahydrate, 28.66g of nickel acetate tetrahydrate, dissolve the powder according to the ratio of 400ml of acetic acid and 100ml of water for every 100g of acetate, pour into In the solution holding dish of the negative pressure suction filter, select a filter membrane with a pore size of 0.45 μm to carry out negative pressure suction filtration, filter out the impurity precipitate in the solution, and obtain Mn 1.56 co 0.96 Ni 0.48 o 4 Precursor solution, and put the solution into a storage bottle for later use.

[0024] 2. Preparation of manganese-cobalt-nickel-oxygen film. Using the homogenizer device in alumina (Al 2 o 3 ) prepared Mn on the substrate 1.56 co 0.96 Ni 0.48 o 4 After each spin-coating of the film, use its self-heatin...

Abstract

The invention discloses a glue mixing machine with a pre-annealing function. The glue mixing machine comprises a glue filling device, a heating device, a heat abstractor and a glue mixer, wherein the glue filling device is used for simplifying a manual glue dropping process into a control process of simple switch motion of a normal close type water valve, so that the glue dropping efficiency is improved, and the problem caused by experience-based glue dropping is avoided; the heating device is used for heating a sample and achieving a low-temperature pre-annealing function of a film; the heat abstractor is used for cooling an inner container of the glue mixer, promoting the exchange of heat and gas inside and outside the heating device, and discharging escaping organic substances after heating; the glue mixer is used for realizing glue throwing operation when the film is prepared. The glue mixing machine provided by the invention has the advantages that a film preparing experiment process of glue dropping, glue throwing and low-temperature pre-annealing in a sol-gel method is simplified into a film preparing experiment process of repeating glue dropping, glue throwing, low-temperature pre-annealing and then concentrated high-heat treatment with a rapid annealing furnace, so that the film preparing time is shortened, and the film preparing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a glue homogenizer, in particular to a glue homogenizer with pre-annealing function. Background technique [0002] The sol-gel method is an important preparation method of thin film materials, which has the advantages of low synthesis temperature, convenient doping, flexible and controllable experimental conditions, and low cost [see Reference 1]. This method generally requires the use of a homogenizer (for spin-coating the precursor solution onto the substrate) and a rapid annealing furnace (for heat treatment of the sample), which requires manual dispensing, spinning, low-temperature thermal annealing, high-temperature Annealing and other experimental processes [see reference 2]. In its traditional application, the law has the following room for improvement. [0003] The first thing that needs to be improved is the manual dispensing and spin-coating process. Before each heat treatment process, it is necessary to use a glue...
