info

Refractory chemicals

Calcium oxide is used as a high-temperature refractory material for lining furnaces and crucibles due to its high melting point and thermodynamic stability.

info

High temperature chemicals

Used in high-temperature chemical processing and as a flux in metallurgical applications to remove impurities from molten metals.

info

Evaporation materials

Calcium oxide is utilized as a source material in vacuum evaporation processes to create thin films for protective or optical layers.

info

Sputtering

CaO targets are used in sputtering processes to deposit thin dielectric films or as a component in complex oxide thin-film research.
