Samples for training 型號：Samples for training

The samples are disks with 0, 1, 2, or 3 Pt electrodes or bars without electrodes or with Pt end-face electrodes. The electrodes are made with commercial Pt-pastes and may have Pt mesh embedded. The samples are uniaxially cold-pressed and subsequently sintered to >90% density. The ceramic powders are mostly commercial state-of-the-art supplies or spray-pyrolyzed.
