Sol-gel silica

  "id": "MLC-T-CHM-010985",
  "term": "Sol-gel silica",
  "field": "Chemistry",
  "definition": "A form of silica prepared through the sol-gel process, involving the hydrolysis and condensation of silicon alkoxide precursors like tetraethyl orthosilicate. The process begins with a colloidal suspension (sol) that evolves into a continuous solid network (gel) containing a liquid phase. After drying and heat treatment, the resulting material is a porous, amorphous silica glass with a high surface area.",
