The effect of particle shape on mechanical properties of perlite/metal
After heating and subsequent expansion, the irregular shape of expanded perlite particles is a projection of the shape of the unexpanded particles. The as-received expanded perlite particles have irregular elongated, platy, or near spherical shapes (see Fig. 1 a). Expanded perlite has a highly porous structure with about 95% internal porosity.Herein, a new green method to prepare the V2O5-immobilized perlite nanocomposite (perlite/V2O5 NC) with sphere-shaped morphology in ethylene glycol under thermal conditions was described.The variation of zeta potential of perlite with electrolyte

Floatable photocatalyst LaFeO3/modified expanded perlite
The floatable photocatalyst LFO/MEP composite can be an effective method for the photodegradation of ammonia. The photocatalyst could be easily recovered and is reusable for several cycles of treatment. EP has a lower adsorption capacity than unexpanded perlite [30]. The surface hydroxyl group is important for a material to have a In this study, electrokinetic properties of unexpanded (UEP) and expanded (EP) perlite samples have been extensively investigated as a function of concentration of various electrolytes such as NaCl, KCl, LiCl, NaNO 3, NaCH 3 COO, MgCl 2, CaCl 2, BaCl 2, Na 2 CO 3, Na 2 SO 4, AlCl 3, FeCl 3, CoCl 2, CuCl 2 and Pb(NO 3) 2.The zeta Zeta potential of unexpanded and expanded perlite samples

Expanded perlite is not only amazingly light weight, but also has exceptional physical properties. Unexpanded (raw) perlite has a bulk density around 1,100 kg/m3 (1.1 g/cm 3), while typical expanded perlite has a bulk density of about 30 –150 kg/m3. Perlite is used in industry in both the forms-Crude Perlite and Expanded Perlite.
