Rational design of perlite-bauxite-based low-density ceramic proppants for hydraulic fracturing
To develop lightweight ceramic proppants and to promote the high-value utilization of two different forms of perlite, this study employed raw perlite and expanded perlite as partial substitutes for bauxite and fabricated low-density proppants via disk ...

steel research international, Volume 97, Issue 8, Page 4067-4084, August 2026.This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Zeolite synthesis in basic media using expanded perlite and its application in Rhodamine B adsorption [PDF]
, 2018 In this work, expanded perlite was employed as a Si and Al source in zeolite synthesis. The products obtained were mixtures of three zeolitic topologies identified by X-ray diffraction and scanning electron microscopy.

Intraspecific Hybridization Improves Performance of the Biological Control Agent Hypena opulenta
Evolutionary Applications, Volume 19, Issue 8, August 2026.ABSTRACT Introduced species often undergo genetic drift and natural selection, which can reduce genetic diversity and drive differentiation among populations. Intraspecific hybridization, outcrossing among individuals from genetically distinct groups, may counteract these effects by increasing heterozygosity, potentially improving performance. However,

Fire barrier based on expanded perlite composites
Modern Building Materials, Structures and Techniques (MBMST), 2019 Decreased strength of building materials as a result of flame impingement (e.g. during a fire) is one of major threats in the construction branch. For these reasons, the effectiveness of fire safety systems in various kinds of facilities or structures is extremely important.

A new consolidation process for expanded perlite particles
Construction and Building Materials, 2014 Abstract A new process for expanded perlite particle consolidation with starch binder is studied for building material applications. Compressive modulus and strength of manufactured perlite foams were characterized for a range of foam densities (0.1–0.4 g/cm 3 ) and compared with gypsum. Compressive strength of perlite foam with a density of 0.3 g/cm
