Usage
In China it is mainly used in these fields:
  1.Building:natural concrete light aggregate. Like heat insulation and preservation materials ,floor,wallboard,active addition and so on.
  2. Chemical Industry: filtering medium,desiccant,catalyst,molecular sieve carrier.
  3. Plastics and Padding Industry
  4. Others: pesticides carrier,fertilizer control agent.
 


 In foreign countries it is mainly used in following fields:
  1.Building Materials: as padding can reduce weight and increase refract ability.
  2.Abrasive Industry: mainly as abrasive and polishing composition.
  3.Daily-Use Chemical Industry: beauty materials,padding of cosmetics,toothpaste,soap and so on.
  4.Petrochemical Industry: as padding of rubber,asphalt,paper making,paint and so on.
  5.Heat Insulator: pumice is the main material, we can get mineral wool product after high melt which is used as ceiling sound insulation.
