The word Prasiolite comes from the Greek words meaning Leek Stone. It is also known as Green Quartz or (incorrectly) called lime citrine. Less common names for the mineral are Vermarine and Amagreen.
Faujasite silica is another form of crystalline silica. It is obtained by dealumination of a low-sodium, ultra-stable Y zeolite with a combined acid and thermal treatment. The resulting product contains over 99% silica, has high crystallinity and high surface area (over 800 m 2 /g).he solubility of silicon dioxide in water strongly depends on its crystalline form and is 3â4 times higher for silica than quartz; as a function of temperature, it peaks at about 340 Â°C.
