It is found in various parts of the world, vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times than its original volume when heated at 850 °C.Vermiculite is most widely used in its exfoliated form. The concertina-shaped granules of exfoliated vermiculite are non-combustible as well as being insoluble in water and all organic solvents.1.construction vermiculite2.Size:0.3-11-2,2-4mm 3.Raw and expanded vermiculite4.Expansion ratios:7-11times1.Description:NameVermiculiteColorGold or silverSize0-30um0.3-0.6mm0.65-1mm0.3-1mm0.5-1.5mm0.5-1.2mm1.2-3.5mm1.5-2.5mm1-2mm2-4mm3-6mm3.5-7mm,4-8mm,etcFeaturespoisonless, odorless , corrosion-resistant, Non-combustible , naturalrefractoryproperties , Goodthermalinsulation , lowdensity ,etc2.Chemical properties:Chemical quota: Mg x (H2O)(Mg3-x)(ALSiO3O10)(OH2)MolecularformulaSiO2MgOAI2O3Fe2O3FeOK2OH2OCaOPHLoss in burning 800°C/HourContent37-42%11-23%9-17%3.5-18%1-3%5-8%7-18%1-2%7-84.5-7.5%3.Physical properties of expandedVermiculite:heet DensityExpanded vermiculite PorosityHard-nessMeltingpointCompressiveresistanceIndex ofrefractionMoisturecontentMoistureabsorbencyAnticongelationAntibio-ticityCorrosionresistanceKg/m3Kg/m3°CMpaNg=1.525-1.561%%1100-1200110-2801-1.51320-1370100-150Ng=1.545-1.5817< 2goodgoodAlkali-resita.Reletive humidity 100% 24H.b.
