context_page_description: A lime kiln is a kiln used for the calcination of limestone to produce the form of lime called quicklime. The chemical equation for this reaction is
  CaCO₃ + heat → CaO + CO₂
  This reaction takes place at 900 °C, but a temperature around 1000 °C is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
  Slaked lime can be formed by mixing quicklime with water.
context_section_description: A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is
  CaCO₃ + heat → CaO + CO₂
  This reaction takes place at 900 °C (1,650 °F) (at which temperature the partial pressure of CO₂ is 1 atmosphere), but a temperature around 1000 °C (1800 °F; at which temperature the partial pressure of CO₂ is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
  Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water.
