Usage

Description

Barium zirconate is a light gray-buff powder that is insoluble in water and alkalies, and slightly soluble in acid. It is a chemical compound with the formula BaZrO3, and it has unique properties that make it suitable for various applications across different industries.

Uses

Used in Electronics:
Barium zirconate is used as a material for gas sensing performance in thick films, particularly for detecting ammonia gas. Its nano powder form enhances the sensitivity and reliability of gas sensors, making it a valuable component in the electronics industry.
Used in Energy Production:
Barium zirconate is used as an electrolyte in solid oxide fuel cells (SOFCs), which are a type of fuel cell that converts chemical energy from a fuel into electricity through an electrochemical reaction. The yttrium-doped barium zirconate improves the efficiency and performance of these fuel cells, contributing to the development of clean and sustainable energy sources.
Used in Manufacturing:
Barium zirconate is used in the production of a white, easily colored silicone rubber compound that exhibits good heat stability at temperatures up to 500°F (260°C). This makes it an essential ingredient in the manufacturing of various products that require high-temperature resistance and flexibility.

Flammability and Explosibility
