calcined

[หˆkรฆl.saษชnd ]

Definition

Context #1 | Verb

chemistry process

Calcined refers to the process of heating a substance to a high temperature but below its melting point, causing thermal decomposition or phase transition. This is commonly used in metallurgy and ceramics to remove volatile substances. The process causes changes in the physical and chemical properties of materials, making them more useful for industrial applications. Calcination can also enhance the reactivity of materials, which is crucial in many chemical processes.

Synonyms

heated, roasted, sintered.

Examples of usage

  • The limestone was calcined to produce quicklime.
  • Clay is often calcined before being used in pottery.
  • The metal ore was calcined to retrieve pure metal.
  • Calcined alumina is used in the production of ceramics.

Interesting Facts

Science

  • Calcination is important in chemistry, especially in the production of metals from ores.
  • This process is often used in the production of cement, where limestone is heated to create lime.

Industrial Applications

  • Calcined products are foundational in industries such as steel, ceramics, and glass manufacturing.
  • Bauxite ore must be calcined to produce alumina, a key ingredient in aluminum production.

Environmental Considerations

  • Calcination processes often produce carbon dioxide, contributing to greenhouse gas emissions.
  • Modern techniques aim to reduce the carbon footprint associated with calcination.

Cultural Significance

  • In ancient civilizations, calcined materials were pivotal for creating pottery and tools.
  • Archaeological findings show that calcined bones can reveal insights into dietary habits of past societies.

Origin of 'calcined'

Main points about word origin

  • The term comes from the Latin word 'calcinare', which means 'to burn lime'.
  • Historically, lime needed to be calcined to be used in construction and agriculture.

The term 'calcined' derives from the Latin word 'calcinare', which means 'to burn or heat'. This Latin term further comes from 'calx', meaning 'lime' or 'lime from ashes', which was crucial in ancient metallurgy. The process of calcination has been used since antiquity, particularly in the production of lime from limestone, which was necessary for constructing buildings and other structures. As the understanding of chemistry progressed, the term evolved to encompass a broader range of materials and methods used in heating processes that change the composition or physical structure of substances. The modern scientific application of the term is widely utilized in various industries, including mining, ceramics, and metal production.
