Beschreibungen/Notizen

• Tin dioxide (SnO2, cassiterite) is one of the few simple oxides that do not react with alumina below a eutectic at 1620°C in air. Consequently it has been of interest for weak interfacial coatings on alumina for ceramic‐matrix composites (CMCs). However, at low oxygen potentials in the Al–Sn–O ternary system an oxidic eutectic liquid containing dissolved tin appears at 1045°C and readily attacks the alumina; this bears some resemblance to liquid phenomena encountered in the Ag‐HTSC (high‐temperature superconductor) systems.
