Abstract

Abstract:

In order to make full use of the carbide slag generated in the production of acetylene gas and realize the resource utilization of solid waste，the needle-like calcium carbonate was prepared from carbide slag by leaching with ammonia chloride solution and NH₄HCO₃ as carbonizing agent.The effects of reaction temperature，dropping mode，dropping speed，the ratio of ammonia and carbonization-agent and calcium ion on the shape of the calcium carbonate were studied.The results showed that the needle shaped calcium carbonate was prepared when the reaction temperature was 80 ℃，n（NH₃·H₂O）:n（HCO₃^-）:n（Ca²⁺）=2:2:1，calcium ion was added to bicarbonate radical solution at the rate of 1 mL/min，and the reaction time was 30 min.The aspect ratio of the product was 8.322 6 and the particle size（D₅₀） was 4.200 μm.The purity of calcium carbonate was 97.20%.Without crystal shape control agent，needle-like calcium carbonate was achieved by adjusting process parameters，which provided reference for the practical application of preparing needle-like CaCO₃ from carbide slag in terms of reducing raw material cost and reducing environmental pollution in the future.

Key words: carbide slag, calcium carbonate, needle-like
