LiAlSi

PetaHte, also a monoclinic lithium aluminum siHcate, LiAlSi O Q, has a theoretical Li O content of 4.88%. Commercial ores usually contain 3.5—4.5% Li O without concentration and ate a preferred source of lithia for use in ceramics and specialty gla2es. PetaHte is monoclinic and has a density of 2.4—2.5 g/cm. Heating to high temperature results in an irreversible phase change to a P-spodumene—Si02 soHd solution that could provide an extractable source...

The structure has often been described with an origin shift and also with reference to LiAlSi as prototype.

The high-quartz and keatite-type alumino-silicates are such stuffed derivatives. Both types of framework are relatively dense, compared with, for example, those of tridymite and cristobalite. Therefore, only small univalent or divalent M ions can be accomodated in their cavities, Li ions being typical. Indeed, solid solutions of the composition LiAlSi 02x4-2 exist with both types of framework over wide ranges of x.
