【摘要】：球霰石以其獨特的機械、物理和化學(xué)性能,在日用品與生物醫(yī)學(xué)等領(lǐng)域表現(xiàn)出廣闊的應(yīng)用前景。然而在三種無水碳酸鈣晶體中,球霰石的熱力學(xué)性能最不穩(wěn)定,在后續(xù)的反應(yīng)和處理過程中常常轉(zhuǎn)變?yōu)楦�(wěn)定的文石或方解石,因此如何抑制球霰石向穩(wěn)定晶型轉(zhuǎn)變一直都是碳酸鈣領(lǐng)域研究的熱點。本文在概述了球霰石晶體結(jié)構(gòu)、性質(zhì)、應(yīng)用及其轉(zhuǎn)化途徑的基礎(chǔ)上,以碳酸鈣的三種基本制備體系為線索,綜述了碳化法、復(fù)分解法、微乳液法和溶劑熱法等傳統(tǒng)方法以及自組裝單分子膜法、仿生合成法和熱分解法等一些新型調(diào)控制備球霰石相方法的研究進(jìn)展,還就利用添加劑促進(jìn)球霰石形成與穩(wěn)定的相關(guān)機制加以剖析。文章旨在為球霰石相碳酸鈣的有效制備提供理論和實踐的參考。
[Abstract]:Because of its unique mechanical, physical and chemical properties, vermicelli is widely used in the fields of daily necessities and biomedicine. However, among the three kinds of anhydrous calcium carbonate crystals, the thermodynamic properties of vermicelli are the most unstable, and in the subsequent reaction and treatment, they are often transformed into more stable aragonite or calcite. Therefore, how to inhibit the transformation of vermicelli to stable crystal form has always been a hot spot in calcium carbonate field. Based on an overview of the crystal structure, properties, applications and transformation approaches of vaterite, the carbonation method and double decomposition method are reviewed, taking the three basic preparation systems of calcium carbonate as clues. Some new methods, such as microemulsion method and solvothermal method, as well as self-assembled monolayer membrane method, bionic synthesis method and thermal decomposition method, have been developed to control the preparation of pellet phase. The mechanism of using additives to promote the formation and stability of pellet is also analyzed. The purpose of this paper is to provide a theoretical and practical reference for the effective preparation of calcium carbonate.
