How It Compares
Within the aluminosilicates and zeolite frameworks class.
Within the diverse family of aluminosilicates, Al8O36Pb8Si8 occupies a distinct niche compared to classic structural minerals like Al2SiO5 or the common framework silicate NaAlSi3O8. While many members of this class are wide-gap insulators, the inclusion of lead in this specific structure imparts a semiconducting character that sets it apart from the more conventional alkali and alkaline-earth aluminosilicates like KAlSiO4 or Ca2Al2SiO7.
