Pyrolytic Boron Nitride (PBN) Rod
PBN1278
New product
Pyrolytic Boron Nitride (PBN) Rod is a high thermal conductivity and high precision clamping rod for electron tubes. The thickness direction of the clamping rod is the growth direction of pyrolytic boron nitride i.e. perpendicular to the growth substrate surface direction, and the width direction is parallel to the substrate surface direction.
