Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18-hydrate Al2(SO4)3.18H2O.Both forms are soluble in water, noncoustible, and nontoxic.The primary hazard is the threat to the environment. Immediate steps
The chemical‐structural properties of synthetic calcium silie hydrate (C‐S‐H) with C/S (Ca/Si) ratios of 0.75, 1 and 1.33 were studied after gamma irradiation‐absorbed doses ranging from 0.145 to 0.784 MGy and compared with those of control specimens.
Calcium silie hydrates possess a remarkable level of structural complexity. Over 30 crystalline phases are known, and for preparations near room temperature, there is an indefinite range of semi-crystalline to nearly amorphous phases, all of which are
Silie definition is - a salt or ester derived from a silicic acid; especially : any of numerous insoluble often complex metal salts that contain silicon and oxygen in the anion, constitute the largest class of minerals, and are used in building materials (such as cement

As nouns the difference between magnesium and magnesium is that magnesium is a light, flammable, silvery metal, and a chemical element (syol mg) with an atomic nuer of 12 while magnesium is a light, flammable, silvery metal, and a chemical element (syol mg) with an atomic nuer of 12.
They are non-ferromagnesian minerals and act as storehouse of sodium, calcium, potassium and many trace elements in soils. In feldspars, the basic structure (Fig. 2.5) is of ring type and made up of four tetrahedra. In two of the tetrahedra, the apical oxygen’s

Calcium scale can look pretty harmless, but it can cause real damage to your pool. Check out our guide to removing calcium scale form your pool fast. Calcium scale, sometimes also called limescale, “is a hard, off-white chalky substance often found on the metallic parts of water-operated machinery.”

Amphibole, any of a group of common rock-forming silie minerals. General considerations Amphiboles are found principally in metamorphic and igneous rocks. They occur in many metamorphic rocks, especially those derived from mafic igneous rocks (those containing dark-coloured ferromagnesian minerals) and siliceous dolomites.
