Lämpödekompositio

Lämpödekompositio, also known as thermal decomposition, is a chemical process where substances break down into simpler substances when heated. It is a type of decomposition reaction that occurs without the involvement of any other chemical agent. The energy required to break the chemical bonds comes from heat.

This process is distinct from combustion, which is a rapid chemical reaction between a substance and an oxidant, usually oxygen, to produce heat and light. Lämpödekompositio, on the other hand, can occur in the absence of oxygen. Examples of lämpödekompositio are common in nature and industry. For instance, when wood is heated in a closed container, it undergoes lämpödekompositio to produce charcoal, volatile organic compounds, and gases.

In industrial applications, lämpödekompositio is used in various processes. Pyrolysis, a form of lämpödekompositio, is used to break down organic materials into valuable products like biofuels, char, and syngas. In metallurgy, heat is used to decompose metal oxides or carbonates into pure metals. For example, limestone (calcium carbonate) is heated to produce lime (calcium oxide) and carbon dioxide. The temperature at which lämpödekompositio occurs varies greatly depending on the substance being decomposed. Some materials decompose at relatively low temperatures, while others require very high temperatures.
