CO2 (Carbon Dioxide)

Notas

In the context of ceramic chemistry, carbon dioxide (CO2) is categorized as a volatile component that is eliminated during the kiln firing process. As it does not persist in the final matured glass or ceramic body, it is excluded from glaze calculations and assigned a zero-weight value, as it contributes no functional properties to the finished material. The presence of CO2 in material analysis primarily serves to quantify components that contribute to loss on ignition (LOI). Within the kiln atmosphere, CO2 is frequently generated during reduction cycles or incomplete combustion, where carbon monoxide (CO) reacts with oxygen-bearing compounds, effectively stripping oxygen atoms to form stable CO2 gas. Chemically, the molecule consists of a single carbon atom covalently double-bonded to two oxygen atoms; it exists as an odorless gas at standard room temperature and pressure.
