| Abstract |
| Because of the poor crystalline nature and presence of interlayer
water molecnles in many phyllosilicates, special pre-treatment as well
as analytical procedures are required. One of these procedures consists
of lyophilizing the sample before analysis. It is stressed that
phyllosilicate samples should not be polished as it risks to cause
structural disorganization.· The acceleration voltage recommended is
15 kV. Few representative micrographs of vermicnlite mineral are
presented for comparison. |
