  • Perlite Imerys

    Used in the construction industry, perlite is a good thermo-acoustic insulator for cavity walls and a valuable, low density fire retardant additive, ideal for meeting current trends Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons. During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite is a microstructure occurring in many common grades Pearlite - WikipediaPerlite 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. Perlite - Wikipedia

  • A synopsis about perlite as building material - ScienceDirect

    2016年9月15日  Perlite is a common name for amorphous volcanic silicate/alumina rock which can be expanded when rapidly heated at 900–1200 °C. Utilization occasions of When perlite ore is expanded, it takes on a low-density cellular structure that makes it a highly efficient high-temperature insulation method. This Use of Perlite in High Temperature Applications: The 2024年1月22日  Perlite is a volcanic glass that, under thermal treatment, expands, producing a highly porous and lightweight granular material which finds application in the Insights in the Physicochemical and Mechanical Properties and

  • Perlite Institute - A Worldwide Association of Perlite

    Why Perlite Works. ly heating perlite ore to temperatures of about 900°C (1,700°F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like 2018年11月14日  Perlite is an amorphous volcanic alumina-silicate rock that expands when rapidly heated to nearly 900 o C. Both the ore and the expanded product have extensive and widespread industrial...(PDF) Evaluation of the Use of Perlite in IndustryFind Perlite for Industry. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular Industrial - Perlite Institute
