In pots, it keeps everything loose, aerated and well draining. On the surface: perlite can be scattered on the surface of the soil as well, where it acts as a wicking agent. It will gradually work down into the soil, improving drainage. For root cuttings: it encourages root growth much better than just plain water.
Perlite filter aids are processed at a temperature exceeding 800. 0. C (1500. 0. F) which eliminates Organic matter, They have extremely low solubility's in mineral and organic acids at both low and high temperatures. Solubility in strong …
Following this expansion, the prior art separates the eX- panded perlite from a gas stream by means of a cyclone separator. This cyclone separator separates out both coarse and fine expanded perlite, which is packaged together. However, the cyclone separation produces a harmful effect upon the perlite in the gas stream.
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing.
