Product Description
Product Introduction
Calcium Titanate (CaTiO₃) is an advanced inorganic ceramic material with a stable orthorhombic perovskite crystal structure, widely used in the electronic and functional ceramics industries. As a titanate-based compound, it offers excellent thermal stability, dielectric properties, and chemical resistance, making it suitable for a wide range of high-performance ceramic applications.
Calcium Titanate is primarily used in the manufacture of dielectric ceramics, microwave devices, PTC thermistors, and electroceramic components. It serves as a key additive or base material to enhance the electrical behavior and structural integrity of ceramic systems. With its consistent crystal structure and high compatibility with other titanates such as BaTiO₃ and SrTiO₃, CaTiO₃ is ideal for blending into customized formulations to meet specific engineering demands.
Our CaTiO₃ powder is engineered to offer high purity, controlled particle size, and superior sinterability. It is suitable for a variety of forming techniques including dry pressing, tape casting, extrusion, and screen printing. The material is also utilized in emerging technologies such as capacitor dielectrics, infrared sensors, and catalyst supports.

Product Application
Calcium titanate (CaTiO₃), as an important electronic raw material, is widely used in the production of PTC thermistors (Positive Temperature Coefficient Thermistor). PTC thermistors are resistor materials with positive temperature coefficient characteristics, and their resistance increases with increasing temperature. Calcium titanate has excellent electrical properties, thermal stability and antioxidant ability, making it an ideal choice for manufacturing PTC thermistors. The following are the applications of calcium titanate in PTC thermistors:
1. Key materials for PTC thermistors
Calcium titanate has a high positive temperature coefficient (PTC) and plays a role in regulating temperature sensitivity in PTC thermistors.
When the temperature rises, the resistance of calcium titanate-based PTC thermistors increases rapidly. This feature makes it very important in applications such as overcurrent protection and temperature protection.
2. Application in electrical appliances and electrical protection
Calcium titanate-based PTC thermistors are widely used in power circuits, home appliance circuits, and automotive circuits as temperature control and overcurrent protection components, which can effectively prevent electrical equipment from being damaged by overload or overheating.
For example, in the fields of motor protection, fuse replacement, switching power supply, etc., calcium titanate materials can effectively limit current and avoid circuit failure.
3. Improve thermal stability and reliability
As a PTC thermistor material, calcium titanate has strong thermal stability. Even in high-temperature working environments, it can maintain good electrical properties and ensure long-term stable operation of the equipment.
Suitable for application environments that require high-temperature stability and durability, such as battery protection, automotive electrical systems, and electronic components.
4. Widely used in overload protection
As an overload protection element, calcium titanate-based PTC thermistors are widely used in electrical equipment such as power electronic equipment, transformers, and relays. When the current is too large, the resistance value increases, thereby limiting the current flow and effectively preventing the circuit from being damaged.
