Soda-lime glass, also called soda-lime-silica glass, is the most prevalent type of glass. The soda-lime glass contains 70% of SiO2 accompanied further by CaO and Na2O.
The chemical ordering is very strong; each silicon atom is connected to four oxygen atoms and each oxygen atom is shared by two silicon atoms as shown below.
Note, Si - pink and O - red
Vitreous Silica only has SiO2 bonded similarly to soda-lime glass but does not have the same impurities as soda glass.
In soda-silica glass, the continuity of the network is disrupted by the addition of Na2O ions.
These make the network more sophisticated and difficult for the atoms to arrange themselves in suitable configurations for crystallization to occur, forming non-crystalline structures.
Describe the difference between vitreous silica and soda-lime glass. What are some advantages and disadvantages of each of these types of glass?
