Conductive Zirconia Ceramics: BZTA ceramics type Z
"BZTA ceramics type Z" is high-strength and high-toughness conductive zirconia-based ceramics
with adjustable electrical conductivity from milliohms to gigaohms.
Features
We already have conductive zirconia ceramics “LPEX,”
but as conductive zirconia ceramics that have high strength and widely adjustable electric resistivity,
we have developed the “BZTA ceramics type Z” under a new concept.
