Description
Calcium Copper Titanate (CaCu₃Ti₄O₁₂, CCTO) Micron Powder
Purity: ≥ 99.5%
Average Particle Size (D50): 1–3 µm
Product Description
Calcium Copper Titanate (CaCu₃Ti₄O₁₂), commonly referred to as CCTO, is a ceramic oxide material known for its exceptionally high dielectric constant—exceeding 10,000 at room temperature. With a cubic crystal structure and excellent chemical stability, CCTO is widely researched and used in next-generation capacitive and energy storage systems.
The material’s unique dielectric properties are attributed to internal barrier layer mechanisms, making it especially valuable for dynamic random-access memory (DRAM) components, multilayer ceramic capacitors (MLCCs), embedded passive devices, and high-energy density capacitors.
