Attention fuel cell manufacturers! A specialized manufacturer of high-performance ceramic substrates.
We will manufacture zirconia ceramic substrates with toughness and ionic conductivity in a thin form.
Utilizing the toughness of "bendable ceramic substrates," we offer them as "next-generation ceramic substrates," enhancing their value as components. Bendable zirconia Ultra-thin zirconia ceramic substrate Zirconia possesses strong toughness (characteristics). By combining it with the manufacturing technology of ultra-thin ceramic substrates from a specialized high-performance ceramic substrate manufacturer, we can achieve bendability while maintaining its ceramic nature. The ultra-thin ceramic substrate (thickness: 50μm) also has transparency, offering possibilities such as achieving thinner substrate layers.

basic information
To the development personnel who are expected to focus on properties such as toughness and ionic conductivity: - Zirconia (ZrO2) excels in corrosion resistance and heat resistance. - It is particularly superior in terms of fracture toughness and bending strength compared to alumina (Al2O3). - Oxide ion conductors (stabilized zirconia) are used in applications such as: - Optical communication connector parts - Ceramic cutting tools - Grinding ball media - Stabilized zirconia as an oxide ion conductor is used for oxygen gas sensors to detect oxygen concentration in exhaust gases. Development for the next generation (expectations): - Zirconia substrates are expected to be developed into ultra-thin substrates, leveraging their strength in fracture toughness to overcome the challenges of miniaturization in electronic components.
