Metakaolin is a dehydroxylated form of the clay mineral kaolinite. Metakaolin is commonly used in the production of ceramics, but is also used as cement replacement in concrete. Metakaolin has a smaller particle size (∼1–2 μm) and higher surface area compared with portland cement, but a larger particle size than SF.

The permeation rate is determined to be 1.6×10 −2 cm 3 m −2 day −1 for oxygen (OTR) under a controlled environment of 70% humidity and 70 °C [159]. Due to these very low permeation rates and the low process temperature, the Al 2 O 3 /ZrO 2 nanolaminate is able to provide encapsulation for OPV devices [159]. 5.2.2.
