名稱 沸石	Name  Zeolite
化學公式  Mx/n[(AlO2)×(SiO2)y].z H2O   y ≥ x	Chemical Formula  Mx/n[(AlO2)×(SiO2)y].z H2O   y ≥ x
莫氏硬度  4.5	Mohs scale of Hardness  4.5
描述  沸石相對較軟，可以壓碎成粉。沸石礦物最常見的有方沸石，菱沸石，斜發沸石，絲光沸石，鈉沸石，赤鐵礦，輝石和閃鋅礦。沸石的顏色為透明，白色，黃色，粉紅色，紅色。沸石的條紋是白色的。它的光澤是玻璃的。	Description  Zeolites are relatively soft and can be crushed and powdered. Most common zeolite minerals are analcime, chabazite, clinoptilite, mordenite, natrolite, heulandite, phillipsite and stilbite.The colour of zeolite is colorless, white, yellow, pink, red. The streak of zeolite is white. Its luster is vitreous.
小挑戰  沸石是如何形成的？ 由於鹼性和地下水之間的反應，天然沸石形成在火山岩上。	Challenge  How zeolite forms? Natural zeolites form on volcanic rocks due to the reaction between alkaline and groundwater.
