Niobium crucible has a variety of uses, as follows:
1. Research and experiment fields:
• Material synthesis and analysis: In the laboratories of universities and scientific research institutions, niobium crucible is often used in the synthesis of various materials, such as the synthesis of new ceramic materials, intermetallic compounds, etc.Its high temperature resistance and corrosion resistance can ensure that the crucible is not eroded by the reactive substances during the experiment, and ensure the accuracy of the experimental results.For example, when synthesizing high-temperature ceramic materials, it is necessary to react and sintering at high temperatures, and niobium crucible can withstand such a high temperature environment.
• Elemental analysis and detection: in spectral analysis, chemical analysis and other experiments, niobium crucible can be used as a sample container.Because of the chemical stability of niobium, it will not pollute the sample, which can ensure the reliability of the analysis results.For example, in atomic absorption spectrometry, the sample is heated in a niobium crucible to atomize it for detection.
2. Industrial production field:
• Metal smelting and casting: In the metal smelting industry, niobium crucible can be used to melt and refine some special metals, such as titanium, zirconium, etc.The melting point of these metals is high, and the requirements of the melting environment is high, niobium crucible can meet its melting needs, and will not react with the metal to ensure the purity of the metal.
• Semiconductor manufacturing: In the semiconductor industry, niobium crucible can be used to manufacture semiconductor materials, such as silicon, germanium, etc., purification and single crystal growth process.In the high temperature, high vacuum environment, the niobium crucible can remain stable, providing a reliable container for the production of semiconductor materials.
• Glass manufacturing: In the glass industry, niobium crucible can be used for the melting and molding of glass.The production of glass requires a high temperature environment, and the niobium crucible can withstand the high temperature erosion of the glass molten liquid, and will not affect the composition of the glass, ensuring the quality of the glass.
3. High temperature treatment field:
• Heat treatment: In some high-temperature heat treatment processes, such as annealing and quenching of metal materials, niobium crucible can be used as a heating container.Its good high temperature resistance and thermal stability can ensure the smooth process of heat treatment.
• High temperature sintering: In the sintering process of powder metallurgy, ceramic materials, etc., niobium crucible can be used to hold powder materials and sintering at high temperatures.It can withstand the high temperature and pressure during the sintering process, providing a stable environment for the sintering of materials.
4. Aerospace field: The aerospace field has extremely high performance requirements for materials, and niobium crucible can be used in the process of manufacturing aerospace parts.For example, in the manufacture of superalloy parts, niobium crucible can be used to melt and cast alloy materials, ensuring the quality and performance of the parts.
