The influence factors of barium carbonate crystal morphology - Appropriate chemical industry
barium carbonate is hexagonal fine crystals or white powder, widely used in electronics, instrumentation, and metallurgical industry, is a manufacturer of optical glass materials. The influence factors of barium carbonate crystal morphology has a lot of, barium carbonate manufacturers qualitative analysis was carried out on the production process, barium salt concentration and temperature will have an effect on the crystal morphology.
barium carbonate manufacturer studies show that when the barium ion concentration is 0. 01, present a acicular barium carbonate crystal, when the concentration increases to 0. 05, barium carbonate crystal morphology not to have the obvious change, but the length decreased significantly, when the concentration increases to 0. 1, crystal reunion phenomenon is serious, particle size distribution, morphology and particle size had no obvious change, if the concentration increased to 0. 5, barium carbonate crystal is present a prism, and reunion. And different raw material, the best concentration of have a little gap.
temperature is also a major factor to influence the barium carbonate crystal morphology, when reaction at room temperature, crystal needle, the reaction temperature increased to 40, the morphology and particle size of barium carbonate crystal does not take place obvious gap, there is no reunion phenomenon occurs, when the temperature reaches 70, barium carbonate crystals appear reunion phenomenon, crystal length decreases, the morphology change.
in addition, barium carbonate manufacturers also studies the influence of reaction time of barium carbonate morphology, with the increase of reaction time, the morphology and particle size of barium carbonate crystal did not change significantly, barium carbonate manufacturers adopts the direct settlement method has nothing to do with the reaction time, is formed in an instant.
barium carbonate manufacturers at this stage is mainly the production of lightweight barium carbonate and heavy barium carbonate, these two kinds of barium carbonate on the industrial application are also different, so the downstream enterprises in the purchase, have to be multifaceted understanding of barium carbonate, choose suitable barium carbonate.
