Примеры

Vermikuliit on vilgukivi meenutav helepruunikas pehme läikiv kivim, mida kasutatakse mullasegudes niiskuse hoidmiseks ja õhustatuse parandamiseks. Vermikuliit tõstab mõnevõrra kasvupinnase aluselisust, mistõttu väheneb lupjamistarve. Ka vermikuliidi mahukaal on väike, mistõttu seguneb halvasti turbaga.

Это интересно

When rapidly heated to about 300° C (570° F), vermiculite can expand to 20 times its original thickness; its name, from the Latin word meaning “to breed worms,” alludes to this property. In its natural state the mineral has little commercial use, but exfoliated vermiculite is extremely light (specific gravity as low as 0.09) and is used in lightweight concrete or plaster, for thermal and acoustic insulation, or as a packing medium, a soil conditioner, a starting medium for seeds, and a filler or extender in paper, paint, or plastics.
