A scientist examines a sample of zirconium dioxide under bright laboratory lights.
Definition
Noun: 1. A white crystalline oxide compound: A chemical compound consisting of the elements zirconium and oxygen (ZrO₂). It is characterized by its white color and crystalline structure, and it possesses properties such as high strength, high melting point, and resistance to wear and corrosion.
Usage Examples
- Noun:
- The exceptional hardness of zirconium dioxide makes it suitable for use in industrial abrasives.
- Zirconium dioxide is a key component in the production of certain high-temperature ceramics.
- Due to its biocompatibility, zirconium dioxide is used in some dental crowns and implants.
Advanced Usage
- "Stabilized zirconium dioxide": Refers to a form of ZrO₂ where its crystal structure is stabilized (often with yttrium or magnesium oxides) to prevent cracking, making it even more useful for engineering applications like thermal barrier coatings.
- The turbine blades are coated with stabilized zirconium dioxide to withstand extreme heat.
