Crucibles are essential tools in various industries, especially in laboratories and manufacturing processes. They need to be made from materials that can withstand extreme temperatures and remain chemically inert. This ensures that the substances they contain are not contaminated.
4 Key Materials Crucibles Are Made Of
Platinum and Platinum Alloys
Platinum is a popular choice for crucibles because of its high melting point and chemical inertness. It is often alloyed with other metals to enhance its durability and resistance to thermal shock. Platinum crucibles are ideal for use in laboratory settings where purity of the substance being melted is critical, such as in analytical chemistry.
Zirconium
Zirconium is another material used in crucibles, known for its high resistance to corrosion and excellent thermal stability. Crucibles made from zirconium are suitable for applications where the material being melted is highly reactive or requires a very high melting temperature.
Silicon Carbide
Silicon carbide is a ceramic material that is extremely hard and has excellent thermal conductivity and resistance to high temperatures. Crucibles made from silicon carbide are often used in industrial applications where the crucible needs to withstand harsh conditions and high thermal loads.
Ceramics and Metallic Components
Inert ceramics and certain metallic components are also used to make crucibles, especially in industrial settings. These materials are chosen for their ability to resist chemical reactions with the contents of the crucible and their high melting points. For example, mullite crucibles, which are made from sandy clay, were historically used in steel production due to their ability to withstand high temperatures and their chemical compatibility with molten metals.
