feed grade zinc oxide

Description

Detailed offer Description Molecular formula:ZnO Molecular weight: *1.*9 Item Index Zinc oxide(counted by dried subtances )%≥ ****9.7 Metal ( zn ) %≤ *9.***0.1 Lead oxide( Pb ) %≤ 0.****0.**7 Cd %≤ 0.**1 Arsenic %≤ 0.***5 Sieve Residue(**0um) %≤ *9.***9.9 Properties: white /slight yellow fine powder, specific gravity 5.5ï&frac*4;6.5, melting point ***5℃, Zinc oxide evaporates in ***0 ℃ . it is amphoteric oxide insoluble in water, ethanol and ammonia, soluble hydroxide and ammonium chloride, while heated, it becomes yellow and resumes white after cooling down. It is lower cost to make the feed additive with the zinc oxide. The zinc oxide compares with the other zinc source, the unit zinc cost is obviously low, favors to reduce the feed cost, the adding amount is equivalent to the monohydrate zinc sulfuric acid *4%, seven water zinc sulfuric acid *8%. Zinc oxide is the powdery zinc source, stability is good in the feed, non- moisture, not lumping, invariability, convenient for the feed processing and the long-term storage. To make zinc oxide as zinc source is easy to be absorbed by the animal compare with other zinc source. It can make up the zinc effect to be good. Uses: It is suitable for supplementary zinc food additive in various kinds of feed such as birds, domestic animal, and fish’s feed etc.
