| Molecular Weight: | 60.0843 |
| InChI: | InChI=1S/O2Si/c1-3-2 |
| Molecular Structure: |  |
| Properties | |
| Melting Point: | 3110 deg F |
| Solubility: | Insoluble Silica is rather poorly soluble in water although solubility is higher for the amorphous than for the crystalline morphologies. ... The external amorphous layer in quartz is more soluble than the crystalline underlying core. AMORPHOUS IS SOL IN ALKALIES, ESP WHEN FINELY DIVIDED |
| Color: | Amorphous powder Transparent to gray powder (Note: Amorphous silica is the non-crystalline form of O2Si). ... solid Silica gel is a coherent, rigid, continuous three-dimensional network of spherical particles of colloidal microporous silica. |
