Nano-CaCO₃ was producted by using carbide slag in the self-designed jet-reactor. The effect of different operating parameter such as CO₂ flow rate and concentration, liquid flow rate and concentration of Ca(OH)₂ on the CaCO₃ particle size and morphology has been investigated in this paper. The obtained calcite particle were characterized using x-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the calcite about 50–200 nm was obtained under the reaction conditions of the saturation of calcium hydroxide as 1, the flow rate as 1.5 l min⁻¹, the CO₂ flow rate as 50 ml min⁻¹, the concentration as 100%, and the SDS amount 2%.

通过在自行设计的喷射反应器中使用碳化物炉渣来生产Nano-CaCO ₃。本文研究了CO ₂流量和浓度，液体流量和Ca（OH）₂浓度等不同操作参数对CaCO ₃粒径和形态的影响。使用X射线衍射（XRD）和扫描电子显微镜（SEM）对获得的方解石颗粒进行表征。结果表明，在氢氧化钙饱和度为1，流速为1.5 l min ^-1，CO ₂流速为50 ml min ^-1，浓度为1.0 mg / mL的反应条件下，获得了约50-200 nm的方解石。为100％，SDS为2％。
