Calcium titanate is widely used in the electronics industry due to its dielectric properties, making it suitable for ceramic capacitors and microwave devices. It serves as a key component in the production of specialty ceramics that require high thermal stability and electrical insulation. The compound is also employed in catalyst support systems, where its structural integrity at high temperatures enhances catalytic efficiency. In materials science, calcium titanate is investigated for use in coatings and composites designed for extreme environments, such as aerospace and high-temperature industrial equipment. Additionally, it finds application in environmental technology, particularly in the immobilization of hazardous metals in solid waste due to its stable crystal structure.
