<p>The invention relates to the production of a silicate having the properties which are similar to the properties of a talcum powder. Said invention makes it possible to produce the silicate (the general formula n*SixOy*z) which can be used instead of natural talc, and to produce substances of various classes based thereon, for example antiseptics, sorbents etc. The inventive method consists in the following: a crushed raw material or crushed glass is treated by water or solutions having an acid or neutral reaction, until pH reaches a value equal to or less than seven in a surface layer of particles of the obtainable product. Afterwards, said particles are removed from the obtained solution. The crushed raw material or crushed glass can also be treated by water or solutions having an alkaline reaction, until pH reaches a value equal to or less than seven in a surface layer of particles of the obtainable product. Afterwards, said particles are removed from the obtained solution. The methods for drying the obtainable product and cleaning the raw material are also disclosed.</p> |
