zr

Thân thiện

A scientist holds a small sample of the metallic element zr.

Definition

Noun: A lustrous grey strong metallic element resembling titanium; it is used in nuclear reactors as a neutron absorber; it occurs in baddeleyite but is obtained chiefly from zircon.

Usage

This word is a highly specific scientific term. It is used almost exclusively in technical contexts such as chemistry, metallurgy, and nuclear engineering to refer to the chemical element zirconium. It is the standard symbol for this element in the periodic table and in scientific notation.

Examples

• The cladding of the nuclear fuel rods is often made of an alloy containing zr.
• The chemical analysis confirmed the presence of zr in the mineral sample.
• Zr has a high resistance to corrosion.

Advanced Usage

• In scientific formulas and equations, zr is used to represent the element zirconium in its elemental form or in compounds (e.g., ZrO₂ for zirconium dioxide).
• The term is often used attributively to describe materials or properties related to zirconium, such as "zr alloy" or "zr content."

Variants and Related Words

• Zirconium (n): The full name of the element for which zr is the symbol.
• Zircon (n): A common mineral that is a major source of zirconium.
• Baddeleyite (n): A less common mineral that also contains zirconium.

Synonyms

• Zirconium (This is not a true synonym but the full name of the element represented by the symbol zr.)

Notes

Zr is a chemical symbol, not a typical word. It is always written with a capital 'Z' and a lowercase 'r'. It does not have associated idioms, phrasal verbs, or multiple meanings in common language. Its use is confined to scientific and industrial domains.
