First of all, from the perspective of product structure, niobium crucibles are usually made of niobium metal materials, with a round or square appearance and equipped with a lid and legs. Since niobium crucibles are easy to deform when used at high temperatures, their bottoms are generally thicker. In addition, niobium crucibles can be made into various sizes and shapes according to different usage requirements.
Next is the question of how to choose the product. When choosing a niobium crucible, we need to consider the following factors: first, the quality of the crucible, including its purity and processing quality; second, its physical properties, such as density, thermal expansion coefficient, etc.; third, chemical properties, such as corrosion resistance, oxidation resistance, etc.; finally, usage scenarios, such as the use temperature range, whether customization is required, etc.
