· JVASP-11013· CaTi2O5

CaTi2O5 is a calcium titanate ceramic compound that belongs to the family of titanate ceramics, which are valued for their structural stability and thermal properties at elevated temperatures. While not a commodity material, calcium titanates are investigated for applications requiring refractories, thermal barrier coatings, and high-temperature structural components where chemical inertness and phase stability are critical. Engineers consider titanate ceramics when conventional oxides prove inadequate under thermomechanical stress or in environments requiring resistance to thermal cycling and chemical attack.
