摘要
红辉沸石属斜方晶系，a=1．36，b=1．81，c=1．78nm，V=4.394nm3。化学成分分析结果（％）：SiO258．76，Al2O314.13，CaO8．80，K2O0．11，Na2O0．18，Fe2O30．44，H2O+16．87，H2O1．25。计算的化学式为：（K0.017Na0.042Ca1.13）1.189［Al1.997，Si7.05，O18」·6．75H2O。Si／Al=3．53.N。=1．501，Nβ=1．495，Nγ=1．488。D=2.13g／cm3（实测）。钾离子（K+）交换量9．34～13·08mg／g，氨离子（NH4+）交换量92.76～130．26mmol／100g。佛石晶体呈透明一半透明，为乳白色、瓷白色。单晶体呈板状、板柱状，集合体呈放射状、束状。单晶体长度可达30cm以上，但通常为5～15cm。红辉沸石呈脉状产出在断裂带中，矿体中沸石含量达95％以上，矿石的白度为91．7。它是一种质量较好、用途较广的极为罕见的沸石矿，也是国内外目前唯一具有工业意义的红辉沸石矿床。
The stellerite is of orthOrhombic system. a = l. 36, b= 1. 81, c = 1. 78nm, V= 4. 394nm3.Chemical composition of the stellerite gave: SiO2 = 58. 76%, Al2O3 = l4. 13 %, CaO= 8. 80 %, K2O= 0. 11 %, Na,O=0. l8%, Fe,O3=0. 0O4%, H2O = 16. 87%, and H2O= l. 25%, Si/Al=3. 53.Crystallochemical formula is (K0.017,Na0.042,Ca1.13 ) l. 189 LAl1.997Si7.05,O18] 6. 75H2O. Na= 1. 5Ol, Nβ=1. 495, Nγ= l. 488, D= 2. 13g/cm K+ exchange amounts: 9. 34~ 13. 08 mg/g. NH4 exchangeamounts; 92. 76~ 130. 26m mol/1OOg.Stellerite crystal is translucent to transparent and has a ceramic-white and greasy-whitecolour. The crystal of stellerite is tabular in habit. The form of aggregate is radiated. A single crys-tal is more than 3O cm in length. But, most of it is 5～15 cm. It occurs as veins in the fault-frac-tured zone. The content of stellerite in the orebody is more than 95 percent. Degree of white in theorebody is 9l. 7. It is a very rare zeolite ore which is of good quality and various application. It isa deposit of stellerite which possesses only industrial importance both at home and abroad at thepresent time.
