Noun
Context #1 | Noun

mineral composition

Periclase is a mineral that primarily consists of magnesium oxide (MgO). It forms through the alteration of dolomitic limestone and is often found in metamorphic rocks. Due to its refractory properties, periclase is used in the production of magnesium oxide bricks for high-temperature environments.

Synonyms

magnesium oxide, periclase mineral

Examples of usage

  • The periclase in the refractory bricks enhances their durability.
  • Geologists studied the periclase crystals present in the rock sample.
  • Periclase is often a significant component in certain types of dolostones.
  • The occurrence of periclase indicates certain geological conditions.

Etymology

The term 'periclase' originated from the Greek word 'periklasis,' which means 'to break around,' reflecting its breaking features under specific conditions. It was first described in the early 19th century by the German mineralogist Friedrich Mohs. Periclase was identified as a distinct mineral due to its unique crystal structure and high melting point. Its significance grew with the advancement of industrial processes that utilized refractories, where periclase's high resistance to heat became invaluable. As industries expanded, especially in steelmaking and glass production, the demand for periclase increased, leading to more extensive studies and applications of this mineral in various high-temperature processes.
