Crystal litter is made from silica gel, an absorbent material that helps trap moisture and odors. Unlike some other types of litter, this one doesn't clump so you'll need to change out the whole pan of litter on a regular basis to prevent odors from forming.
Sand is a loose, fragmented, naturally-occurring material consisting of very small particles of decomposed rocks, corals, or shells. Sand is used to provide bulk, strength, and other properties to construction materials like asphalt and concrete.
The making of a Silicon wafer: With all this talk of sand and glass it may begin to over simplify a very complex process.
