To use measurements of chlorophyll fluorescence to analyse photosynthesis, researchers must distinguish between photochemical quenching and non-photochemical quenching (heat dissipation).
By varying the heat treatment to include water or liquid nitrogen quenching, or omitting the normalization heat-treat to permit work hardening, properties can be improved.
Due to the high temperature and rapid quenching, sanidine can contain more sodium in its structure than the two polymorphs that equilibrated at lower temperatures.
For example, appropriate quenching of steel can convert a desirable proportion of its content of austenite to martensite, creating a very tough product.
Upon final quenching a metastable austenite is retained in the predominately ferrite matrix along with small amounts of bainite (and other forms of decomposed austenite).
