Ob chav siv lead ua, (3) ntev tau Ishinari solutionwith calcium uas yuav ua tau rau albite ntxaib tab sis 80-85% sodium feldspar. Alkali feldspar Petrologyare orthoclase, pob zeb microcline, albite andtrondhjemite los yog cov feldspar tau solutionsynthesized xws li, feldspar thiab albitepercentages cov uas tsis muaj 80%. K-feldspar(orthoclase or microcline), albite, krespectively (Al Si3O8) thiab naj (Al Si3O8). Molecular mis ntawm cheebtsam Anorthite CaAl2 Si3O8.Anorthite thiab albite yuav tsim tau hais haum, ntxhia namely hu ua plagioclaseminerals ~ sodium lossis calcium uas feldspar.
