Interesting facts about tantalum
Are you interested in interesting facts about tantalum and its alloys from the supplier company AvecGlob? Here you will find interesting information on this topic.
General information
Tantalum is classified as a refractory metal because of its high melting point. It has low vapor pressure and good electrical and thermal conductivity at very high temperatures. Advantages of tantalum — excellent corrosion resistance, high temperature, good workability and good biocompatibility.
Tantalum is a strong, viscous metal that is almost immune to chemical attack at room temperature. It can be pulled into a thin wire, which is used to vaporize metals, such as aluminum. Because of the high melting point, tantalum is often used as a substitute for platinum.
Tantalum can be alloyed with steel to increase steel ductility, strength and melting point.
Industrial application
Tantalum is an element that is used in practice, improving the technologies and material characteristics of many alloys. Its numerous applications include use in electronics, medicine, engineering and energy production.
About half of consumed tantalum is used annually in the electronics industry, mainly as a powder and wire for capacitors, thanks to the special ability of tantalum to store and release electrical energy. This allows components to be extremely small, and therefore they are preferred in highly space-sensitive locations, in the field of telecommunications, data storage and implantable medical devices. Tantalum is also used for electronic sound filters and as a barrier against the diffusion of copper in semiconductors. The hardness of tantalum carbide makes it ideal for cutting tools. Tantalum is used for the manufacture of components of chemical plants, nuclear power plants, aircraft and rockets. Since it does not react with body fluids, it is used to make surgical equipment. Tantalum also does not irritate the body, and is therefore used to make surgical sutures, as well as implants such as artificial joints and cranial plates.
