cristobalite

As nouns the difference between cristobalite and tridymite

is that cristobalite is a mineral of volcanic rocks that solidified at a high temperature. Cristobalite is chemically identical to quartz, with the chemical formula SiO₂, but has a different crystal structure. Crystals are always microscopic, and usually form small rounded masses while tridymite is a rare mineral of volcanic rocks that solidified at a high temperature, with the chemical composition silicon dioxide, SiO₂. Tridymite is chemically identical to quartz, but has a different crystal structure. Sometimes contains sodium aluminum silicate, which seems to be expelled when quartz solidifies at lower temperatures.
