• Chemische Eigenschaften

  Perlite is a natural glass formed by volcanic action. It is a sodium potassium aluminosilicate that has an amorphous structure. It possesses an unusual physical characteristic of expanding to about 20 times its original volume when heated to temperatures within the softening range, somewhere between 1400 and 2000 ℃. Expanded perlite is either a fluffy, highly porous substance or a glassy-white particulate with low porosity, depending on how the material is heated. The bulk material has a density between 3 and 20 lb/ft3.
  The crystalline silica content of 16 samples of perlite ore collected from 19 deposits in 16 western states was quite low, ＜2% in 15 and 3% in one sample. The crystalline silica content of typical expanded perlite ranged from 0 to 2%.

• Verwenden

  It is used in abrasives, acoustical plaster and tile, charcoal barbecue base, cleaner base, concrete aggregates, filter aids, fertilizer, metal foundries, insulation, and refractory products. It is used as a filler in numerous materials. Incorporation into construction materials accounts for about 70% of the domestic use of perlite.

• Verwenden

  Filter aid, Harborlite 800 is used in multiple industrial applications such as chemical processing, mineral and lubrication oil production, biodiesel purification. It is also used for filtration performance in brewing, juices, wine, sugar syrups, edible vegetable and fish oils.

• Sicherheitsprofil

  Slightly toxic by ingestion. A nuisance dust.
