Binary crystals are found in several click here structures. Some pairs of aspects variety more than one composition. At place temperature, cadmium sulfide may perhaps crystallize possibly from the zinc blende or wurtzite structure. Alumina also has two probable buildings at room temperature, α-alumina (corundum) and β-alumina. Other binary crystals show various structures at diverse temperatures. Among the many most sophisticated crystals are These of silicon dioxide (SiO2), which has 7 distinct buildings at many temperatures and pressures; the most common of such buildings is quartz.
