Meaning and Definition
A type of glass made primarily from silicon dioxide (SiO₂) with high purity, known for its thermal shock resistance and transparency to ultraviolet light.
A material used in scientific, industrial, and specialty applications (e.g., laboratory equipment, fiber optics, telescope mirrors) due to its low thermal expansion and high chemical durability. Informally, may refer to any clear, high-purity glass.

Common Mistakes When Using “silica glass”
- Using 'silica glass' to refer to ordinary window glass (which is soda-lime glass).
- Pronouncing 'silica' as /saɪˈlaɪkə/ instead of /ˈsɪlɪkə/.
- Treating it as a countable noun (e.g., 'a silica glass') instead of an uncountable material name.
FAQ
Frequently Asked Questions
No. Regular window or container glass (soda-lime glass) contains silica plus soda and lime, which lower its melting point but reduce thermal and chemical resistance. Silica glass is primarily pure silicon dioxide.
Yes, but it has an extremely high melting point (around 1700°C), much higher than ordinary glass. It is often referred to as 'fused' silica glass because it is made by melting high-purity silica sand or quartz crystals.
Because of its high purity, it allows light signals to travel long distances with minimal loss or attenuation, which is critical for telecommunications.
They have the same chemical composition (SiO₂) but different structures. Quartz is a crystalline mineral. Silica glass (fused quartz) is the amorphous, non-crystalline form created by melting and rapidly cooling quartz, giving it glass-like properties.
A type of glass made primarily from silicon dioxide (SiO₂) with high purity, known for its thermal shock resistance and transparency to ultraviolet light.
Silica glass is usually technical/scientific in register.
Silica glass: in British English it is pronounced /ˈsɪlɪkə ɡlɑːs/, and in American English it is pronounced /ˈsɪlɪkə ɡlæs/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think of SILICA (like 'silly car' but 'silly ca' from the beach sand, silicon) + GLASS (what you see through). 'Silly car made of see-through glass from sand' hints at its main component and transparent nature.
Conceptual Metaphor
MATERIAL IS PURITY (e.g., 'the lens is pure silica glass' implies superior optical quality).
