Temperature related:
Temperature range: Select the appropriate electric furnace based on the temperature range required for CVD coating experiments. If the experiment requires a higher temperature, it is necessary to ensure that the electric furnace can reach and maintain this temperature stably. The highest temperature for quartz tube CVD can reach 1200 ℃, which can meet various high-temperature coating experiments.
Temperature accuracy: In order to obtain high-quality coatings, an electric furnace is required to provide accurate temperature control. Fuzzy PID control and other technologies can achieve temperature field uniformity and ensure the consistency of sintered products.
Furnace structure:
Furnace tube material: Quartz furnace tubes are suitable for high temperature and corrosive environments, and the selection should consider the process conditions and required gas environment.
Other structures of the furnace body: Choosing a furnace with a reasonable structure, such as a double-layer air-cooled mechanism, flanges sealed with clamps, etc., can improve the stability and durability of the furnace. At the same time, the selection of furnace materials is also important. Materials such as high-purity alumina, polycrystalline pure fibers, etc. have the advantages of cleanliness and energy saving, and are suitable for CVD coating experiments.
Gas supply system: It should be able to mix multiple gases and accurately control the intake volume. Float flow meters and mass flow meters can be used to estimate and control the intake volume, ensuring a stable supply of gas during the experimental process.
Vacuum system: provides the necessary vacuum environment for CVD experiments. Choose a suitable vacuum device, such as a low vacuum system or a high vacuum system, based on the required vacuum level and cleanliness for the experiment.
Safety: Ensure that the furnace has comprehensive safety protection measures, such as overheating protection, power-off protection, etc., to prevent accidents during the experimental process.
Brand and after-sales service: Choosing reputable brands and suppliers to provide stoves can ensure the quality of products and the reliability of after-sales service.
