Effect of heat treatment on preparation of expanded perlite from Indonesian perlite rock

AIP Conference Proceedings, 2021
Expanded perlite is a multifunctional material that has been widely used in Industry. Its light, porous, and high-temperature resistance has made it well known used for lightweight and fire-resistant materials. In this study, the expanded perlite was prepared from perlite rock originally from Padang Pariaman district, West Sumatra, Indonesia, by ...

Development of granular expanded perlite/paraffin phase change material composites and prevention of leakage

Solar Energy, 2016
In this study, granular phase change material (PCM) composites were developed by absorbing paraffin into the pores of expanded perlite particles with two grades of particle size. Because of the different particle sizes and pore structures, the absorption

Development of Expanded Perlite Board for Thermal Insulation

Chiang Mai Journal of Science, 2022
In this study, the perlite-based insulating material is developed to meet ASTM C610 standards in a form of the board. Expanded perlite powders with a tapped density of 53 and 150 kg/m³ were used in this study. Sodium silicate used as a proper binder at various concentrations was mixed with perlite powders.

Lightweight Mortars Based on Expanded Perlite

Key Engineering Materials, 2018
Lightweight mortars composed from a lime-metakaolin binder or lime-cement binder and expanded perlite filler were prepared and tested. Mortar test samples were firstly cured in a humid atmosphere and subsequently in laboratory ambient conditions. Development of hardening processes was studied by X-ray diffraction and thermal analysis.

Adsorptive Desulfurization of Crude Oil with Expanded Perlite

Caucasian Journal of Science, 2022
Crude oil; is a fossil energy source that has become possible to be used by refining processes and has a critical importance for the welfare, economic development, and quality of life of the society. As a result of the use of fossil fuels, carbon dioxide (CO2), sulfur oxide (SOx), and other greenhouse gases are released and these gases are expressed as

Preparation and Utilization of Fine Expanded Perlite

Key Engineering Materials, 2007
Hollow glass microspheres named expanded perlite have been prepared from perlite, but the size is usually above 20 µm. 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 particle, which is the origin of foaming, is evolved during ...

Application of Qualitatively Improved Expanded Perlite (Review)

Glass and Ceramics, 2021
A comparative analysis of the physicotechnical properties of existing and proposed perlite heat-insulation products, agricultural components, and acoustic fillings, demonstrating significant improvement in the quality of the latter, is presented. In this connection, a selective method is proposed for developing perlite deposits in thin extraction ...

A chemical evaluation of expanding perlitic rocks

Materials Chemistry, 1976
Abstract A correlation between chemical composition and expansion properties of a number of perlitic rocks is proposed. Samples, which through their mineral norms were represented by points within the silica rich zone on a feldspars-quartz diagram, did not expand properly, whereas a sample of excellent expansibility belonged to the feldspars rich ...

Enhancing thermo‐mechanical properties of epoxy using flake‐like micro expanded perlite particles

Polymer Composites
The physical and thermo‐mechanical properties of polymer matrix composites can be improved by incorporating different organic and inorganic filler materials. In this work, a novel flake‐like filler material, expanded perlite powder, was used to fabricate
