( Brand: Calcium Copper Titanate High K Dielectric ), ( Manufacturer Part Number: 564598 )
Calcium Copper Titanate, also known as High Dielectric Calcium Copper Titanate (CCTO), is a complex perovskite-type oxide material with the chemical formula CaCu3Ti4O12. This inorganic compound is renowned for its exceptional dielectric properties, making it an essential component in various electronic applications.
The microstructure of CCTO is characterized by a tetragonal crystal lattice, where calcium ions occupy the A-site, copper and titanium ions occupy the B-site, and oxygen ions occupy the O-site. The unique arrangement of these ions contributes to the material's high dielectric constant and low loss tangent, making it an ideal choice for capacitor applications.
CCTO exhibits a high dielectric constant, typically in the range of 8000-12000, depending on the specific synthesis method and processing conditions. This high dielectric constant arises from the presence of both oxygen vacancies and interstitial calcium ions in the material's crystal lattice. These defects create a large number of mobile charge carriers, which contribute to the material's high dielectric response.
Moreover, CCTO has a relatively low loss tangent, usually below 0.1, indicating minimal energy loss during the dielectric charging and discharging process. This low loss tangent ensures efficient energy storage and high power handling capabilities.
The synthesis of CCTO can be achieved through various methods, including solid-state reaction, co-precipitation, and sol-gel techniques. The choice of synthesis method depends on factors such as desired purity, particle size, and morphology of the final product.
CCTO is commonly used as the dielectric material in high-voltage capacitors, particularly in power electronics applications such as energy storage systems, power converters, and AC motor drives. Its excellent dielectric properties enable efficient energy storage and power handling, contributing to improved system performance and reliability.
Furthermore, CCTO has potential applications in various other fields, such as sensors, actuators, and dielectric resonators. Its high dielectric constant and low loss tangent make it a suitable material for these applications, where efficient energy storage and response are required.
In summary, Calcium Copper Titanate (CCTO), with the chemical formula CaCu3Ti4O12, is a complex perovskite-type oxide material known for its exceptional dielectric properties. Its high dielectric constant and low loss tangent make it an essential component in various electronic applications, particularly in high-voltage capacitors for power electronics. The material's unique microstructure and defects contribute to its high dielectric response, making it a versatile and valuable material in various fields.
Calcium Copper Titanate (CCTO or CaCu3Ti4O12) is a high dielectric material, specifically a solid solution of the perovskite family. It is known for its excellent dielectric properties, making it a popular choice in the electronics industry for capacitor applications. Here are some pros and cons of buying CCTO:
Pros:1. High Dielectric Constant: CCTO has a high dielectric constant (around 2500-3000) which allows for the manufacture of smaller capacitors with higher energy density.
2. Low Dielectric Loss: CCTO has a low dielectric loss, meaning that it does not dissipate energy as heat when an electric field is applied. This is important for the efficient operation of electronic devices.
3. Stability: CCTO is known for its excellent thermal and electrical stability, making it suitable for use in high-temperature and high-frequency applications.
4. Chemical Resistance: CCTO is resistant to moisture and other chemicals, making it a good choice for use in harsh environments.
Cons:1. Cost: CCTO is a relatively expensive material due to the complexity of its production process.
2. Fragility: CCTO is a brittle material and can be easily damaged during handling or processing. This can increase the cost of production and reduce yields.
3. Toxicity: CCTO contains heavy metals, including calcium, copper, and titanium, which can be toxic in large quantities. Proper handling and disposal procedures must be followed to ensure safety.
In conclusion, Calcium Copper Titanate is a high-performance material with excellent dielectric properties, making it a popular choice in the electronics industry. However, its high cost, fragility, and toxicity are important considerations. If the benefits of using CCTO outweigh the costs for a specific application, then it may be a worthwhile investment. Otherwise, alternative materials with similar properties but lower costs and easier handling may be more suitable.
Recommendation:For applications where high dielectric constant, low dielectric loss, thermal stability, and chemical resistance are essential, Calcium Copper Titanate may be the best choice. However, if cost, fragility, or toxicity are significant concerns, alternative materials such as barium titanate, lead zirconate titanate, or other high dielectric ceramics should be considered. Ultimately, the decision to use CCTO should be based on a careful evaluation of the specific requirements of the application and the associated costs and benefits.
