CE ÎNSEAMNĂ CORDIERITE ÎN ENGLEZĂ?
cordierite
Cordieritul sau iolitul este un ciclosilicat de magneziu de fier de magneziu. Fierul este aproape întotdeauna prezent și există o soluție solidă între cordieritul bogat în Mg și secaninaitul bogat în Fe cu o formulă de serie: 2Al3 până la 2Al3. Există un polimorf de temperatură înaltă, indialit, care este izostructural cu beril și are o distribuție aleatorie a lui Al în inelele 6O18.
Definiția cordierite în dicționarul Engleză
Definiția cordieritei din dicționar este un mineral dicroic de culoare gri sau violet-albastru care constă din silicat de fier de magneziu din aluminiu în formă cristalină ortorombică și se găsește în roci metamorfice. Formula: 2AL4Si5O18.nH2O De asemenea, numit: dichroit, iolit.
