The chemical properties of silica sand is the same as silica gel. The only difference is size of silica sand is slightly smaller than silica gel. Silica sand has diametrer of 0.2- 1 mm. Silica sand is available in porous, granular, and amorphous from, synthetically manufactured from the chemical reaction between sulfuric acid and sodium silicate. The internal structure of Silica sand is composed of a vast network of interconnected microscopic pores which attract and hold water, alcohol, hydrocarbons and other chemicals by the phenomena known as physical adsorption and capillary condensation.

Advantages of Silica Gel

1   Silica sand has ability to adsorb up to one third of its own weight in water vapour. This adsorption efficiency is approximately 35% greater that typical desiccant clays, making Silica sand the preferred choice where weight or efficiency are important factors.
2   Silica sand has an almost indefinite shelf life if stored in airtight conditions.
3   Silica sand can be regenerated and reused if required. Gently heating silica sand will drive off the adsorbed moisture and leave it ready for reuse.
4   Silica sand is a very inert material, it will not normally attack or corrode other materials and with the exception of strong alkalis and hydrofluoric acid is itself resistant to attack.
5   Silica sand is non-toxic and non-flammable.
6   Silica sand is most frequently and conveniently used packed in a breathable sachet or bag. These are available in a wide range of sizes suitable for use with a wide range of applications.

Material Safety Data

Safety Direction

Reaction

  Reactivity is stable under normal temperatures and pressures in sealed containers. Hazardous polymerization will not occur.

Spill

  Clean up personnel need protection against inhalation of dusts or fumes. Eye protection is required. Vacuuming methods of clean up are preferred.

Inhaled

  May cause health hazards when Inhaled, ingested or in contact with the eye and skin. Prolonged Inhalation may cause irritation to the upper respiratory track and lung damage. Contact with eye tissue may result irritation.

Fire

  Nonflammable but negligible fire and explosion hazard when exposed to heat or flame by reaction with Incompatible substances. When fire occurs, use dry chemical, water spray, or foam. For larger fires, use water spray fog or foam.

 

First Aid

Inhalation

  Remove to fresh air immediately. If breathing has stopped, give artificial respiration. Keep affected person warm and at rest. Get medical attention immediately.

Ingestion

  If large amounts have been ingested, give emetics to cause vomiting stomach siphon may be applied as well .Milk and fatty acids should be avoided. Get medical attention immediately.

Eyes

  Wash eyes immediately and carefully for 30 minutes with running water, lifting upper and lower eyelids occasionally. Get prompt medical attention.

Skin

  To avoid repeated or prolonged contact with this chemical, use good hygienic practices. Wash with soap and a large amount or water. Get medical attention if irritation or Inflammation develops.
