Product Description
Product Introduction
Barium Zirconate (BaZrO₃) is an advanced structural ceramic material known for its exceptional chemical stability, high melting point, and excellent mechanical properties. As a perovskite-type oxide, BaZrO₃ exhibits outstanding resistance to thermal shock, corrosion, and wear, making it ideal for demanding industrial applications.
This ceramic material is widely used in harsh environments such as high-temperature fuel cells, chemical reactors, and thermal barrier coatings. Its high melting temperature (~2600°C) and thermal stability allow BaZrO₃ to maintain structural integrity under extreme conditions. Additionally, its low thermal conductivity makes it suitable for insulation and heat-resistant components.
Our Barium Zirconate powder is produced with high purity, fine particle size, and excellent phase stability, ensuring consistent performance and ease of processing. It can be fabricated into dense ceramic parts through sintering, hot pressing, or spark plasma sintering methods. BaZrO₃ is also a promising material for use in proton-conducting electrolytes and dielectric applications due to its ionic conductivity when suitably doped.

Product Applications
Barium Zirconate (BaZrO₃) is a versatile ceramic material with a range of remarkable properties, making it essential in a variety of high-performance applications. As a perovskite oxide, Barium Zirconate is known for its thermal stability, high dielectric constant, low thermal conductivity, and resistance to chemical corrosion. These characteristics make BaZrO₃ particularly valuable in both electronic and structural ceramics.
In the field of dielectrics, Barium Zirconate is widely used in the production of high-frequency capacitors and dielectric resonators. Its high dielectric constant and low dielectric loss make it ideal for use in microwave devices, communication systems, and radar equipment, where reliable signal transmission is critical. It is also used in multilayer ceramic capacitors (MLCCs), where it offers superior performance in high-voltage applications.
Barium Zirconate is also explored as a key material in solid oxide fuel cells (SOFCs), where it serves as an electrolyte or a proton-conducting ceramic. Its ability to conduct protons at high temperatures makes it ideal for energy conversion and storage systems. Additionally, BaZrO₃ is used in the development of ceramic coatings and protective layers for components exposed to high temperatures and aggressive chemical environments, such as gas turbines, combustion chambers, and furnaces. Its excellent resistance to thermal shock and chemical attack helps enhance the longevity and performance of these components.
