Calcium Titanate Sputtering Targets

Calcium titanate (CaTiO₃) sputtering targets are used in a range of high-tech applications due to their unique electrical, optical, and dielectric properties. Here’s a look at some specific product applications for calcium titanate.

Dielectric Materials:

Capacitors: Calcium titanate is often used in the production of thin film capacitors. Its high dielectric constant makes it ideal for creating capacitors with high capacitance values, which are crucial for electronic circuits and memory devices.

Piezoelectric Devices:

Sensors and Actuators: In piezoelectric applications, calcium titanate can be used to produce thin films that convert mechanical stress into electrical signals or vice versa. This property is valuable in sensors, actuators, and transducers.

Ferroelectric Thin Films:

Memory Devices: Calcium titanate is used in ferroelectric memory devices (FeRAM). Its ferroelectric properties allow it to be used in non-volatile memory technology, where data is stored using the material’s ability to maintain an electric polarization.

Optical Coatings:

Anti-Reflective Coatings: Calcium titanate films can be used in optical coatings to reduce reflections and enhance light transmission. This is beneficial in lenses, optical sensors, and other imaging systems.

Thermoelectric Materials:

Energy Harvesting: Calcium titanate can be used in thermoelectric materials that convert temperature differences directly into electrical energy. This application is important in energy harvesting and power generation from waste heat.

Substrate Materials:

High-Temperature Superconductors: Calcium titanate is used as a substrate material for the growth of high-temperature superconducting thin films. It provides a suitable lattice structure that supports the growth of these films.

High-Voltage Insulators:

Electrical Insulation: The high dielectric strength of calcium titanate makes it suitable for use in high-voltage insulators and other components requiring robust electrical insulation.

Catalysts:

Chemical Reactions: In some catalytic processes, calcium titanate films can act as a catalyst or catalyst support, facilitating chemical reactions in various industrial applications.

In these applications, calcium titanate sputtering targets are chosen for their ability to produce thin, uniform films with desirable properties.
