Study Notes
Glass: Definition and Formation
- Amorphous solid, often transparent but can be translucent or opaque.
- Typically hard and brittle.
- Formed by rapidly cooling molten inorganic materials, preventing crystalline structure.
Types of Glass
- Fused Silica Glass (SiO2): Almost pure silicon dioxide; high melting point, low thermal expansion, excellent transparency; used in lenses, prisms, optical fibers, and high-temperature applications.
- Soda-lime Glass (SiO2, Na2O, CaO): Silicon dioxide, sodium oxide, calcium oxide; relatively low melting point, good chemical durability; used in windows, bottles, and containers (most common type).
- Borosilicate Glass (SiO2, B2O3, Na2O, Al2O3): Silicon dioxide, boron oxide, sodium oxide, aluminum oxide; high thermal shock resistance, good chemical durability; used in laboratory glassware and cookware.
