A zirconia crucible is a container made of zirconium dioxide (ZrO2) used for high-temperature applications. Zirconia is a ceramic material that exhibits high resistance to corrosion, wear, and thermal shock, making it an excellent choice for melting and casting metals, alloys, and other materials. Zirconia crucibles come in a variety of shapes and sizes and are commonly used in metallurgy, chemistry, and materials science laboratories. They are particularly useful for high-temperature applications that require low contamination, such as in the production of semiconductor materials, as well as in the study of high-temperature chemical reactions and phase transformations. Zirconia crucibles are also used in the manufacture of artificial teeth and as a dental prosthetic material due to its biocompatibility and aesthetic properties.
