Exempel på hur man kan använda ZEOLITE i en mening

• Analcime is usually classified as a zeolite mineral, but structurally and chemically it is more similar to the feldspathoids.
• Though not a zeolite, prehnite is found associated with minerals such as datolite, calcite, apophyllite, epidote, stilbite, laumontite, and heulandite in veins and cavities of basaltic rocks, sometimes in granites, syenites, or gneisses.
• Further enrichment is only possible by absorbing the remaining water using other means, such as hydrophilic chemicals or azeotropic distillation, or a column of 3A molecular sieves, like 3A zeolite.
• Today, Calgon water softener contains the active ingredient sodium citrate, and the now discontinued powder used zeolite and polycarboxylate, all of which are less problematic in wastewater treatment than phosphates.
• Scolecite is isostructural (having the same structure) with the sodium-calcium zeolite mesolite and the sodium zeolite natrolite, but it does not form a continuous chemical series with either of them.
• Other exposure in the flocking industry can include acrylic adhesives, ammonium ether of potato starch, heat transfer oil, tannic acid, and zeolite.
• Pressure swing adsorption (PSA) oxygen concentrators use a molecular sieve to adsorb gases and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals at high pressure.
• Heulandite was first separated from stilbite by August Breithaupt in 1818, and named by him "euzeolite" (meaning beautiful zeolite); independently, in 1822, H.
• Zeolites other than erionite (clinoptilolite, phillipsite, mordenite, non-fibrous Japanese zeolite, synthetic zeolites).
• At Sankt Andreasberg in the Harz it is found in the lead and silver veins; and at Strontian in Argyll in lead veins, associated with brewsterite (a strontium and barium zeolite), barytes and calcite.
• Cavansite, named for its chemical composition of calcium vanadium silicate, is a deep blue hydrous calcium vanadium phyllosilicate mineral, occurring as a secondary mineral in basaltic and andesitic rocks along with a variety of zeolite minerals.
• The Plateau's minerals include igneous basalt rocks, iron ores (magnetite and hematite), silicates (prehnite, zeolite), apatites, perovskites and highly saturated copper and nickel ores.
• In this case, an aluminum silica based zeolite adsorbs nitrogen in the first stage reaching 95% oxygen in the outlet, and in the second stage a carbon-based molecular sieve adsorbs the residual nitrogen in a reverse cycle, concentrating oxygen up to 99%.
• When heat is called for during the night, or sunless hours, or winter, humidified air flows through the zeolite.
• Early research suggests this mineral has ties to weakly metamorphosed plutonic rocks during formation, and is also found with montmorillonite clays or zeolite crystals.
• First, titanium dioxide made from titanium isopropoxide was impregnated into NaY zeolite powder to give sample W-Ti-NaY.
• The zeolite facies is generally considered to be transitional between diagenetic processes which turn sediments into sedimentary rocks, and prehnite-pumpellyite facies, which is a hallmark of subseafloor alteration of the oceanic crust around mid-ocean ridge spreading centres.
• Clinoptilolite is a natural zeolite composed of a microporous arrangement of silica and alumina tetrahedra.
• It can also be synthesised by isomerization of n-pentane in the presence of a catalyst containing combinations of one or more of palladium, platinum, rhodium and rhenium on a matrix of zeolite, alumina, silicon dioxide or other materials.
• It is a metamorphic grade transitional between zeolite facies and greenschist facies representing a temperature range of 250 to 350 °C and a pressure range of approximately two to seven kilobars.
