설명

일반 설명

Silica gel, highly porous textured matrix are generally used for synthesis of adsorbents. They are corpuscular in structure. Silica surface have a layer of hydroxyl groups and adsorbed water molecules are removed by drying at high temperature or even by treatment with suitable reagents. Silica gel surface plays significant role in catalysis, chemical separation and microelectronic fabrications.

애플리케이션
