Description
Technical field
The present invention relates to field of chemical preparation, and in particular to a kind of producer of the spherical basic cobaltous carbonate of size tunable
Method.
Background technique
Basic cobaltous carbonate [2CoCO3·3Co(OH)2·H2O] it is a kind of aubergine prism sprills, it is dissolved in diluted acid and liquid
Ammonia is practically insoluble in cold water, decomposes in the hot water, is mainly used in and prepares various cobalt products, for example, cobalt powder, cobaltosic oxide,
Cobalt oxide etc., the hot succession very big with the performance some of its presoma cobalt carbonate of the powder such as granularity, the pattern of these cobalt products
Property, and have extensive purposes in fields such as electronics, metallurgy, chemical industry, especially it is used as LITHIUM BATTERY Co in battery industry3O4Forerunner
Body.Meanwhile the preparation process of cobalt acid lithium shows that cobalt acid lithium, which can be improved, using big partial size spherical cobaltic-cobaltous oxide prepared now
The reactivity of journey improves discharge platform, therefore, big four oxidation three of big partial size spherical shape of preparation quality stabilization, spherical morphology, partial size
Cobalt precursor has become research hotspot.
In the development process of basic cobaltous carbonate production method, most original is to carry out production Co by semi-mechanized operation
[(OH)2]a[CO3] 1-a, but the production technology period is long, and washing step time-consuming takes 3-4 days at the soonest, and technological parameter is cumbersome
Complexity is not easy to grasp, meanwhile, drying time is long in the production technology, and temperature distribution is non-uniform, be easy to cause local temperature mistake
Height, product particle is small, reunites serious, spherical shape is poor.So then replaced by a kind of quick basic cobaltous carbonate production technology,
The processing step is substantially are as follows: dissolution, synthesis, filtering, washing, drying；Wherein, cobalt chloride and sodium carbonate dissolve in course of dissolution
Ratio example in mass ratio are as follows: CoCl2:H2O=1:4-8, Na2CO3:H2O=1:4-8；Wherein, aqueous slkali and chlorine in the synthesis process
Changing cobalt liquor takes spray mode to be added, and synthesising reacting time is 2-4 hours.This technological operation is simple, with short production cycle；But
It is that the properties of product produced are unstable, it is oxidizable, and also product particle is uneven, and granularity is small, granularity difficulty control, cobalt tenor
It can only achieve 46%-50%, therefore be unfavorable for efficiently refining production, be easy to produce great waste.Now, and one is developed
Kind produces basic cobaltous carbonate material in such a way that nanometer synthesizes, and the technology is although more advanced, guaranteed to product quality,
But production cost is but very high, requires precision to equipment and instrument, and it is costly, therefore, large area also is done without condition now
It promotes.
