For heat insulation and sound insulation materials, the powder with a humidity of 5% is less than 0.6 tons/m3 (preferably 0.2~0.3 tons/m3).
Humidity less than 10%, silicon dioxide (SiO 2 ) >70%
Catalyst carrier (for sulfuric acid production)
Silica (SiO 2 ) >65%
Ferric oxide (Fe 2 O 3 ) <4%
Loss on ignition <10%
White Ceramic Industry Silica (SiO 2 )>85%
Ferric oxide (Fe 2 O 3 ) <1% (reducing the degree of refractoriness and coloring the finished product, reducing electrical insulation).
The diatomite industry requirements for building materials are shown in the table below.
