Definition

1. Adjective: Relating to or involving chemical reactions that occur at very high temperatures.

Usage

• The pyrochemical process is essential for extracting certain metals from their ores.
• Researchers studied the pyrochemical properties of the compound under extreme heat.
• This is a pyrochemical method for waste treatment, not a biological one.

Advanced Usage

• Pyrochemical reprocessing: A method for recycling nuclear fuel that uses high-temperature molten salts instead of aqueous solutions.
  • The facility specializes in the pyrochemical reprocessing of spent reactor fuel.

Variants and Related Words

• Pyrochemistry (noun): The branch of chemistry concerned with reactions at high temperatures.
  • His research focuses on pyrochemistry and its industrial applications.

Synonyms

• High-temperature chemical
• Thermochemical (Note: While closely related, "thermochemical" often refers more broadly to the heat changes in reactions, whereas "pyrochemical" specifically emphasizes the high-temperature conditions of the reactions themselves.)
