4A Zeolite exhibits as white solid particles.Showed network-like
structure, it contains uniform pores, whose size is around 0.42nm.
Its specific surface area of about 600m2 / R, It can not dissolve
in water or organic solvents, while it can be dissolved in alkali
and acids.Heated above 800 , it will re-form into white
crystalline silica-like structure.4A Zeolite shows abilities of
adsorbing moisture, liquids, gases and non-saturated organic
material.Its theoretical exchange capacity is 352CaCO3mg / g,
typically 290 ~ 320mgCaCO3 / g. Its whiteness ≥ 95%, pH value of 10
~ 11.5, apparent density of 0.3 ~ 0.5g/cm3, and average particle
size of 2μm.
