All About Amorphous Quartz

Silica gel is an amorphous and porous form of silicon dioxide, consisting of an irregular tri-dimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids or may be filled by gas or vacuum. In the latter case, the material is properly called Silica xerogel. Get price

The transformation of amorphous silica to crystalline

Hydrothermal syntheses were made mainly in the binary system SiO2-H2O in a temperature range between 300 C and 500 C and pressures from 0.2 kbar up to 4.0 kbar with various starting materials. In this way the transformation behavior of different amorphous silicas via cristobalite and keatite to quartz were observed. This behavior depends mainly on the parameters: pressure, temperature Get price

Tool Rust Prevention With Containers and Silica Gel

So, some museums and industries prefer the silica gel amorphous granules in irregular shapes because they don't roll away when spilled. Reusing Silica Gel.
