1.Property:
Ammonium nitrate is over99.5%,molecular
formula is NH4NO3,molecular
weight is 80,nitrogen content is 35%,white
granule crystal; the physical and chemical
property of porous ammonium nitrate is similar
to that of ammonium nitrate, but compared
with common crystal ammonium nitrate and granular
ammonium nitrate,it has lower water content,
good fluidity and bulk property, easy to fill
and store, safe and convenient use. 2.Use:
It is mainly used to produce ammonium nitrate
fuel oil explosive which has excellent performances
with low use cost and thus widely used in
mine exploration, construction, railway/road
construction as well as medical, chemical
and other fields. 3.Products features:
High oil absorbency, low water content, and
the explosive produced from them are extremely
powerful. The following table shows the comparison
between our products and standard values:

4.Testing methods
(1)Ammonium nitrate content:Ammonium nitrate
reacts with formaldehyde and generate hexamethylene
tetramine and aid,then use standard sodium
hydroxide solution to titrate the generated
acid to determine the Ammonium nitrate content
(2)Fee water content:Karl Fisher method
(3)Oil absorbence:Soap with light diesel
fuel, and then filter it with glass pot
filter, and then weight the sample after
oil absorption.
(4)Bulk density:Put the sample into container,
and then test the mass/unit (g/cm3).
(5)Granularity:Vibrate the sample in sieve
and screen it, then determine the percentage
of granules at the size of Θ0.5~Θ2.5mm.
(6)10% ammonium nitrate water solution PH:
dissolve the sample in distilled water without
carbon dioxide,then determine the PH with
pH meter.
5.Packing
[Products features] It has many tiny pores, and its oil absorbency is higher than other types of ammonium nitrate, lower water content, good bulking property and easy to be packed
[Standard] HG3280-1990
[Spec.] 25kg/bag or upon clients' requests.
[Packing & storage] In woven bag with plastic lining; stored in dry and airy place in room temperature; kept away from heat source and fire, avoid violent impact.
[Cautions] It can easily absorb moisture and should not be kept in open and humid air for long, aviod contact with metal, oil or other organic substances(exception: it is used to make explosive)
