Analcime (/ əˈnælsiːm, - saɪm /; from Ancient Greek ἀνάλκιμος (análkimos) 'not strong') or analcite is a white, gray, or colorless tectosilicate mineral. Analcime consists of hydrated sodium aluminium silicate in cubic crystalline form. Its chemical formula is NaAlSi 2 O 6 · H 2 O. Minor amounts of potassium and calcium substitute for sodium.

Analcime is a member of the zeolite group, and often occurs together with other zeolites. However, it is closely related in structure to the feldspathoid group, and is occasionally also classified as a feldspathoid together with the similar mineral Leucite.

2024年1月22日 · 方沸石 （英语： Analcime）是一种白色、灰色或无色的 网硅酸盐矿物。 由水合硅酸铝钠组成的立方晶系结晶型态，化学式为Na (AlSi. 6) · H 2 O，其中有少量钠可能会被钾或钙给取代。 另外也存在一种含银的人工合成变种（银方沸石）。 方沸石常被归类为 沸石 族矿物，但在结构和化学性质上它更偏向于 似长石 族矿物 [3]。 方沸石不属于 立方晶系，虽然晶体结构看起来相似，但通常仍偏离了一小部分角度。 然而，也存在着真正的立方晶系的矿物样本，这使 …

Analcime, common feldspathoid mineral, a hydrated sodium aluminosilicate (NaAlSi2O6·H2O) that occurs in seams and cavities in basalt, diabase, granite, or gneiss and in extensive beds thought to have formed by precipitation from alkaline lakes.

According to the International Zeolite Association (http://www.iza-online.org/natural/Datasheets/Analcime/Analcime.html) the mineral has variable composition, which can be given as Na 16-x (H 2 O) 16+x [Al 16-x Si 32+x O 96], with x varying from -3.4 to +4.3. The Na content generally is ~16 atoms per formula unit, but may range from 12 to 17.

经大连理工大学化学物理研究所试验表明，方沸石应用于农牧业、环境保护、建材三大最佳领域的项目有：利用方沸石生产离子筛及橡塑助剂、 土壤改良剂 、重金属提取剂、生产硅铝化合物、杀菌剂、特殊氧化剂等。 方沸石经过化学改性处理后，显示出独具特色的“离子筛”特性，对直径<2.6Å的重金属离子如Cu、Pb、Zn、Ag、Fe等具有选择吸附性，非常适合于此类金属的提取、熔炼及废水净化。 经改性后，方沸石的纯度及孔径均有明显改善，吸附力和离子交换力明显提 …

2020年3月1日 · Natural analcime, a highly brittle aluminosilicate mineral that dissolves easily during diagenesis, occurs in the sedimentary rocks of eight main non-marine petroliferous basins in China. This mineral has been well documented for the past 30 years and has proved to be significant for the formation of high-quality hydrocarbon reservoirs.

Occurs frequently in basalts and other basic igneous rocks associated with other zeolites. From near Catanes, Cyclopean Isles, Italy. Link to MinDat.org Location Data. From the Greek word meaning weak, referring to a weak electrical charge developed on rubbing. Comments: Brownish yellow transparent analcime crystals. Location: Guam.
