Abstract

Abstract:

Nano calcium carbonate is a new kind of important nano material,which is widely used in coatings,rubber,paper-making and other fields.Preparation of different types of nano calcium carbonate particles has always been the research focus. Nano calcium carbonate was synthesized by carbonization method.Glucose,sucrose and soluble starch were used as crystal control agents respectively.The samples were characterized by fourier transform infrared spectroscopy（FT-IR）,transmission electron microscope（TEM）,X-ray diffraction（XRD）.The experimental results showed that the addition of carbohydrates co-uld affect the particle size and morphology of nano-calcium carbonate,due to the high electronegativity of polar-OH groups in the structure of carbohydrates,which could coordinate with Ca²⁺ through charge matching.The effect of different carbohydrates on the crystallization of nano calcium carbonate was explored and reliable experimental data and experience were provided for similar research.

Key words: nano calcium carbonate, crystallization control, carbonization, carbohydrates
