peptisation

Thân thiện

A scientist uses peptisation to prepare a colloidal solution in the lab.

Definition

Noun: * Peptisation: The process of converting a substance into a sol (a colloidal solution); the act of bringing a material into a colloidal state by breaking down aggregates into particles small enough to remain suspended in a liquid medium.

Usage

This is a technical term used primarily in chemistry and materials science. It describes a specific physical or chemical process. * The peptisation of the clay was achieved by adding a dispersing agent. * Peptisation is a crucial step in the preparation of stable colloidal suspensions for industrial applications.

Advanced Usage

• Agent of peptisation: A substance (often an electrolyte or surfactant) that induces or facilitates the peptisation process.
  • Sodium silicate is a common agent of peptisation for silica particles.

Variants and Related Words

• Peptize (verb): To subject to or undergo peptisation.
  • The goal is to peptize the precipitate to form a clear sol.
• Peptizing agent (noun phrase): Synonym for "agent of peptisation".
• Deflocculation (noun): A closely related process where aggregated particles are dispersed in a liquid, often used interchangeably with peptisation in some contexts, though subtle distinctions may exist.

Synonyms

• Deflocculation
• Colloidal dispersion
• Sol formation

Antonyms
