Ionic and covalent bonds are defined by bond length, and in many real compounds the actual bond length is between the ionic and covalent bond lengths. These bonds can be described as some percentage ionic and some percentage covalent. Si-O (called siloxo) bonds in quartz and opal are mostly covalent. Glass is not mostly covalent because it has alkali fluxes that make it more ionic.
Sialate bonds (Si-O-Al-O, where the aluminum has a alkali atom associated with it) are also mostly (but I believe less so) covalent.

What is the chemical form of quartz?
Quartz is silicon dioxide, SiO2.
What is the chemical composition of quartz mineral?
Quartz is silicon dioxide (SiO2).
How do you account for the abundance of quartz?
The mineral quartz is abundant in sedimentary rocks because quartz is very durable and resistant to chemical weathering.
Quartz resists chemical weathering more than any other common mineral?
Quartz is a mineral that is the most resistant to chemical weathering. Its resistance is due to the structure of the grains that comprise it.
What is chemical composition of quartz for electrode?
SiO2 is quartz- a nautural piezo-electric compound when in crystalline form.
Is quartz a physical or chemical property?
Quartz is silicon dioxide (SiO2); quartz is not a property.
What is the chemical system for quartz?
Quartz is silicon dioxide, SiO2.
What is the chemical form of quartz?
Quartz is silicon dioxide, SiO2.
What is the chemical composition of quartz mineral?
Quartz is silicon dioxide (SiO2).
Does the chemical makeup quartz ever change?
No chemical formulas ever change. If there are different elements in a compound, it ceases to remain the same compound, and becomes a new compound.The chemical formula for quartz is SiO2. That is, always was, and always will be the chemical formula for quartz.
What metal is quartz made of?
quartz is not made of a metal, its chemical formula is SiO2
Is a diamond quartz?
No. A diamond is a diamond: quartz is quartz. Both have different chemical elements and different molecular structures.
