Silicon dioxide - Wikipedia
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO 2, commonly found in nature as quartz. [5] [6] In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product.

14.4A: Graphite and Diamond - Structure and Properties
2023年1月16日 · Silicon dioxide is also known as silica or silicon(IV) oxide has three different crystal forms. The easiest one to remember and draw is based on the diamond structure. Crystalline silicon has the same structure as diamond. To turn it into silicon dioxide, all you need to do is to modify the silicon structure by including some oxygen atoms.
GIANT COVALENT STRUCTURES - chemguide

2.6.2 Silicon(IV) Oxide Structure - tutorchase.com
Silicon (IV) oxide is a primary component in glass-making due to its structural properties. The giant covalent structure of SiO₂, where each silicon atom is bonded to four oxygen atoms, results in a material that is both hard and has a high melting point, yet once melted, it becomes highly viscous and can be shaped and moulded.
