AIST develops glass-based dielectric material that operates stably at 300°C
The National Institute of Advanced Industrial Science and Technology (AIST) developed a new material combining glass and niobium oxide that maintains stable dielectric properties across temperature changes up to 300°C. It could enable capacitors to operate in high-temperature environments such as electric vehicle engine compartments.
What happened
ITmedia (MONOist) reported on Aug. 24, 2026, that the National Institute of Advanced Industrial Science and Technology (AIST) developed a new material combining glass and niobium oxide that maintains stable dielectric properties across temperature changes up to 300°C.
Why it matters
AIST developed a material for capacitors that combines glass and niobium oxide and maintains stable dielectric properties even amid temperature changes up to 300°C. Its significance lies in offering an option for components used in conditions where conventional materials struggle to maintain their properties, such as the high temperatures in electric vehicle engine compartments.
