(1)高岭石Al2(Si2O5)(OH)4可写成:______;
(2)正长石KAlSi3O8可写成:______;
(3)滑石Mg3Si4O10(OH)2可写成:______;
(4)钙沸石CaAl2Si3O10?3H2O可写成:______.
(1)高岭石Al2(Si2O5)(OH)4 可表示为:Al2O3?2SiO2?2H2O,故答案为:Al2O3?2SiO2?2H2O;
(2)正长石可表示为KAlSi3O8:K2O?AL2O3?6SiO2,故答案为:K2O?AL2O3?6SiO2;
(3)滑石Mg3Si4O10(OH)2 可表示为:3MgO?4SiO2?H2O,故答案为:3MgO?4SiO2?H2O;
(4)钙沸石Ca(Al2Si3O10)?3H2O 可表示为:CaO?Al2O3?3SiO2?3H2O,故答案为:CaO?Al2O3?3SiO2?3H2O.
(2)正长石可表示为KAlSi3O8:K2O?AL2O3?6SiO2,故答案为:K2O?AL2O3?6SiO2;
(3)滑石Mg3Si4O10(OH)2 可表示为:3MgO?4SiO2?H2O,故答案为:3MgO?4SiO2?H2O;
(4)钙沸石Ca(Al2Si3O10)?3H2O 可表示为:CaO?Al2O3?3SiO2?3H2O,故答案为:CaO?Al2O3?3SiO2?3H2O.
