The rhenium mocvd heater manufacturer tells you that in the process of making superconducting mocvd, the growth of superconducting film ybco needs to reach a high temperature for its growth into a lattice, and a substrate pallet structure with heating function is used. The rhenium mocvd heater manufacturer tells you that in practical applications, the superconducting substrate is attached to the surface (substrate supporting surface) of the aforementioned substrate support, and the metal organic source gas grows high-quality superconducting substrates on the high-temperature superconducting substrate. of superconducting thin films.

However, the alloy metal material used in the substrate support plate used in the past will find that the surface of the high-temperature metal material has strong high-temperature corrosion due to the speciality of the superconducting film, so that the metal growth reaction corrosion occurs, and the reaction interface appears, and the next cleaning The rear substrate pallet (especially the substrate support surface of the substrate pallet) will become thinner and thinner.
The rhenium mocvd heater manufacturer tells you that even after a long time of use, even the high-temperature metal substrate will deform, and it needs to be polished regularly or even scrapped. This leads to abnormal lattice arrangement in the growth of superconducting films, thus affecting the critical current of superconducting tapes.
The rhenium mocvd heater manufacturer tells you that the weight of the single-piece substrate pallet is basically 45-65kg due to the use of high temperature heat-resistant metal, which is very inconvenient for substrate handling and movement. The rhenium mocvd heater manufacturer tells you the thermal shock performance of general ceramic materials It can not meet the needs of continuous production, cracking will occur once or twice under the condition of high temperature, and the mechanical strength is not good, and it will be damaged if it is accidentally damaged.
In response to the above problems, a new type of rhenium mocvd heater is proposed. Its substrate pallet has the advantages of light weight, high wear resistance, corrosion resistance and no deformation. The rhenium mocvd heater manufacturer tells you that it can achieve continuous production stability, low heating cost, Low labor intensity, low cost maintenance, short cooling time and other effects.
