Product Description
Product Introduction
Strontium Zirconate (SrZrO₃) is a high-purity ceramic material with a perovskite-type crystal structure, known for its thermal stability, excellent dielectric properties, and chemical resistance. It is commonly used in advanced electronic ceramics, thermal barrier coatings, and solid oxide fuel cells (SOFCs) due to its unique combination of electrical and structural performance.
SrZrO₃ exhibits a high melting point (>2500°C), making it ideal for high-temperature applications. It maintains structural integrity and insulation capabilities even under thermal cycling or corrosive environments. As a dielectric material, it offers good insulating properties and is often used in capacitors, resistors, and substrates for microelectronic components.

Product Applications
Strontium Zirconate (SrZrO₃) is a highly versatile ceramic material known for its excellent thermal stability, chemical inertness, and high dielectric properties. As a member of the perovskite oxide family, SrZrO₃ is widely used in various advanced electronic, structural, and energy-related applications due to its unique combination of electrical and mechanical properties.
One of the primary applications of Strontium Zirconate is in the electronics industry, where it is used as a dielectric material. SrZrO₃ is often employed in the production of high-performance capacitors, particularly in high-voltage and high-frequency applications. Its high dielectric constant and low dielectric loss make it ideal for use in multilayer ceramic capacitors (MLCCs), dielectric resonators, and microwave components.
In the energy sector, Strontium Zirconate plays a crucial role in solid oxide fuel cells (SOFCs). Its ability to act as a stable electrolyte or proton-conducting material at elevated temperatures makes it an essential component in energy conversion and storage systems. SrZrO₃ is also being explored for use in proton-conducting ceramics, where it provides efficient ion conduction in high-temperature applications, contributing to improved performance in fuel cell technologies.
Additionally, SrZrO₃ is used as a key material in the production of thermal barrier coatings (TBCs). These coatings are applied to turbine blades and other components exposed to extreme heat in gas turbines, jet engines, and power plants. The low thermal conductivity and high melting point of Strontium Zirconate make it an ideal material for protecting components from thermal damage and improving efficiency in these high-stress environments.
In the field of refractories, SrZrO₃ is used for applications that involve high-temperature processes, such as molten metal processing and ceramic kilns. Its ability to resist chemical attack and thermal shock makes it suitable for crucibles, furnaces, and kilns.
Strontium Zirconate’s chemical stability, mechanical strength, and resistance to corrosion at elevated temperatures also make it valuable in environmentally demanding applications in industries such as aerospace, automotive, and chemical processing.
