Plant growth in expanded perlite

New Zealand Journal of Agricultural Research, 1960
Summary The chemical and physical properties of expanded perlite as a growth medium are described. The growth of cress in perlite receiving additions of inorganic fertilisers is described and assessed. Only slightly less growth was made in perlite fortified with plant nutrients than in a good potting soil. The medium is simple to handle and is suitable

Evaluation of expanded perlite behavior in PS/Perlite composites

Applied Clay Science, 2019
Abstract In this study, composites based on PS/Perlite were prepared with 10 (P10) and 20 (P20) wt% of perlite by melt mixing in a twin screw extruder. The perlite effect was assessed by the composites morphological, thermal, mechanical and rheological properties. The photographs obtained by SEM revealed that some perlite's particles broke during the

Preparation of fine expanded perlite

Journal of Materials Science, 1999
Hollow glass microspheres named expanded perlite have been prepared from perlite, but the size is usually above 20 μm. Recently fine microspheres with low density are desired. In the conventional preparation method, it is difficult to produce fine expanded perlite with particle size under 20 μm because the water contained in finely milled perlite ...
