农业用途
Phlogopite is one of the most commonly present micas
and is denoted as K(Mg,Fe)
3AlSi
3O
10(OH,F)
2.Mica is
commonly found as small flakes or lamellar plates
without a crystal outline. Thin cleavage sheets of mica,
particularly muscovite and phlogopite, are elastic,
flexible and tough. They range from translucent to
transparent. They have low electrical and thermal
conductivity and high dielectric strength, and hence are
used as electrical insulators.
