Product Description

Lava stone is formed when the lava stream flows and cools down with the air remains and becomes small holes in the final rock. Lava stone owe the special features such as sound absorbing and insulation,heat absorbing and preservation,water absorbing and slide -proof,acid &alkali proof ,"breathing function".
 
Features:
1)  not radiation 
2)  not permeation 
3)  not poisonous and not odor 
4)  green and environmental-protection products with high quality 
5)  hyperfine and with high quality products
6)  be used to interior decoration,outside decoration and paving publish square 

Application:  
1) It is so called as functional stone which can be used safely in any place for its low radiation,wind erosion -proof and durability,sound absorbing and noise lowering,water absorbing and air humidity keeping,dizzy light avoiding,etc in improving our environment and feelings
2) Therefore,this volcanic stone material can be used widely in outer wall decoration,such as road ,square paving ,living distract gardening,etc to meet our needs of nature,primitiveness,simplicity,classicalism. 
3)We can supply various kinds of finished volcanic stones with differently treated surfaces,such as honed ,polished,bush hammered ,etc.with all kinds of shapes and thickness. 

Volcanic filter material mainly used for water treatment, with irregular partical shape, dark brown or beige color , porosity . The particle size we offer are 2-4mm,3-6mm,5-12mm,12- 18mm or according to customer's requirement.
