Abstract	As for circumstellar dust, Mg-rich silicates such as forsterite and enstatite were mainly detected. Recently, silica SiO2 is detected in debris disks. This referred silica is various crystal types such as quartz, fused quartz, annealed silica. We report on the infrared spectra of various types' silica and discuss on possibility of silica and observation.
