Zeolite

The zeolite The zeolite is the generic term of zeolite family mineral, is a kind of aqueous alkali metal or alkali earth metal's aluminosilicate mineral. Zeolite's density is 1.92-2.8g/cubic centimeter, moss scale of hardness is 3.5-5.57, its color is lighter, mostly is white, light yellow, light green, pale red and sandy beige. The natural zeolite is a kind of emerging material, because it has many technological characteristics, so it is widely used in many departments, and its use will be developed ceaselessly. In the world, there're many kinds of natural zeolites, such as the clinoptilolite, mordenite, lime harmotome, erionite, chabazite and so on. The clinoptilolite and mordenite are our company's main products. Technological Characteristics & Main Uses Technological Characteristics: The ion-exchange property is one of the important characteristics of the zeolite. The K, Na, Ca, etc cations and water molecule in the cavity of the zeolite can not unit tightly with the grillwork, it is extremely easy to occur the exchange interaction with the cation of the aqueous solution that surrounding it. After the exchange zeolite lattice structure is not destroyed. According to verifications, the NH4 cation's exchange capacity of the clinoptilolite and mordenite are all high, and the clinoptilolite even can choose to exchange some certain heavy metals, thus it can be used for eliminating heavy-metal ion. Absorbability: zeolit has wide specific surface area(500-1000 sq.m./g), so it has stronger diffusive force, so it can be used as the outstanding adsorbent. The zeolite crystal has many sizable cavities and channels, under certain physical-chemical conditions, these channels can have precise and constant diameter (about 3-11A), those substance which smaller than the diameter can be adsorbed. This phenomenon is called the "molecular sieve" function. But not all the zeolite has the molecular sieve function. Catalysis property: Because zeolite has broad absorption surface, it can hold quite many adsorbing substances, thus it can promote the chemical reaction, so the zeolite also can be used as the effective catalyst and catalytic carrier. Thermal stability: zeolite rock's thermal stability has something to do with the zeolite's cation variety , silica alumina ratio, internal structure and so on factors. Acid resistance: zeolite has good acid resistance. In addition, the zeolite also has chemical reactivity, far-infrared radiation, reversible dehydration property and so on technological characteristics.
