Zirconia: meaning, definitions and examples
🦷
zirconia
[ zɜːrˈkoʊ.ni.ə ]
material science
Zirconia is a white crystalline oxide of zirconium, used as a refractory material and in ceramics. It is also known for its use in dental crowns and in various industrial applications due to its strength and resistance to corrosion.
Synonyms
ZrO2, ceramic material, zirconium dioxide.
Examples of usage
- The dental technician used zirconia to create a durable crown.
- Zirconia is often preferred for its low thermal conductivity in high-temperature applications.
- Researchers are studying zirconia for use in solid oxide fuel cells.
Etymology
The term 'zirconia' derives from the mineral zircon, from which it is obtained. Zircon itself has been used for centuries in decorative jewelry and its name can be traced back to the Persian word 'zargun', meaning 'golden colored'. Zirconium was first identified in 1789 by the Swedish chemist Johan Gottlieb Gahn, who isolated the oxide. The name 'zirconia' was first used in the early 19th century when chemists began to recognize its distinct properties, especially its utility in ceramic and refractor technologies. The advancements in the extraction and application of zirconia have made it a critical material in various industrial sectors, particularly in the field of dental science, where its biocompatibility and aesthetic qualities have been invaluable.
