1、Chemical Name:Sodium Molybdate
2、Molecular Formula : Na2MO4.2H2O
The Sodium Molybdate Dilutions (1% Mo) occurs as a white to faint yellow
powder. The Sodium Molybdate Dihydrate is dissolved in water firstly and then
the carrier(s) such as Calcium Carbonate or Maltodextrin are dispersed into the
solution, and finally spray dried into powder. The mineral salts are enclosed in
the dilutions and their functions are still maintained. The dilutions have many
advantages compared with their pure. The assay of the dilutions and the
carrier(s) can be customized according to customers' demand.
Specification:
3.Features:
1) Appearance: white crystalline power, soluble in water, insoluble in
acetone, dehydration under 100°C
2) Applications: used for catalyst for petrochemical industry, in
metallurgic industry,
it is used for making molybdenum powder, molybdenum bar, molybdenum
wire
and molybdenum plate, it can also used for the microelement of the
fertilizer and
ceramic pigment making and metal surface treatment,raw materials for
pigment
and other molybdenum products
4.Package: In plastic lined knit bags with the net capacity of 25 kg or
double-plastic-bags lined iron drums with the net capacity of 50 kg.
Note: Capable of supplying products with various specifications and
packages according to customers' requirements.
