Usage

1.      A sulfate scavenger in chromium electroplating baths

2.      An oxidizing agent, making it useful as a burn rate modifier in pyrotechnic compositions. It is especially useful in delay compositions such as delay fuses

3.      A corrosion inhibitive pigment when zinc-alloy electroplating surfaces

4.      Used to color paints. The pigment known as lemon yellow often contained barium chromate mixed with lead sulfate

5.      Also used in the composition of a catalyst for alkane dehydrogenation

Application

1.      As a metal or when alloyed with aluminium, is used to remove unwanted gases (gettering) from vacuum tubes, such as TV picture tubes

2.      An additive to silumin (aluminium–silicon alloys) that refines: bearing alloys; lead–tin soldering alloys – to increase the creep resistance; alloy with nickel for spark plugs; additive to steel and cast iron as an inoculant; alloys with calcium, manganese, silicon, and aluminium as high-grade steel deoxidizers.

Application: The product has excellent performance of stability and lubrication. Its stability is stronger than hard calcium, it also has excellent coordination effect when used together with cadmium soap, Zn soap and epoxy compounds. It is mainly used in transparency film, slice, artificial leather, cable granule, mechanically-resistant materials etc. Too much use would result in separation and multi-layer guilloche.

Packing: In10kgor20kgplastic woven bags.
