<p>A mixt. of Si, and a silicate contg. another element such as Mg, and/or Al and/or Ca is used for gritting roads in winter, and for covering oil on water. The silicate is in the form of needle-like crystals of multi-dimensional interlinked bundle structure for producing adhesion between the silicate and one or more other substances and also produces specific friction forces between second and third other substances present. The agent avoids environmental pollution, is economical, and easy to produce.</p> |
