Addition of lime (CaO) and soda (Na2CO3) to the hard water precipitates calcium as the carbonate, and magnesium as its hydroxide. What are the advantages and disadvantages of lime soda? It is slow process because reactions during water softening takes place in very dilute solutions and room ...
摘要: Lime soda ash softening in domestic water treatment works is detailed; includes process chemistry, reagent selection, and schematic illustrations of the implementation of lime soda ash softening.关键词: water softening lime–soda ash process solubility cation removal precipitation–dissolution ...
Soda-lime glass is the glass of windows, bottles, and lightbulbs, used in vast quantities, the most common of them all. The name suggests its composition: 13–17% NaO (the “soda”), 5–10% CaO (the “lime”), and 70–75% SiO2 (the “glass”). It has a low melting point, is...

Soda-lime-silica glass is defined as the most common type of glass composed of SiO4 tetrahedra connected by oxygen atoms, with the addition of network modifiers like Na2O to disrupt the network continuity. It is easy to melt, chemically durable, and cost-effective, with a typical composition ...
Soda lime glasses are susceptible to changes in temperature. Their high coefficient of thermal expansion and low softening temperature cause high thermal stresses and cracking. As a result, they were replaced by a second important family of glasses. In some cases, they are more expensive than ...
