摘要: 以工业硼砂和七水硫酸锌为主要原料,采用沉淀法制备了低水合硼酸锌Zn6O(OH)(BO33。使用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)、热重分析(TGA)等对产物的结构和形貌进行了表征。考察了反应体系pH、反应温度、反应时间、反应物料配比等因素对产物结构和组成的影响,得出制备 Zn6O(OH)(BO33的条件:工业硼砂与七水硫酸锌物质的量比为1∶1,反应pH为7.5~8.0,反应温度为90 ℃,反应时间为6 h。此条件下产品收率达到83%。

Abstract: Low hydrated zinc borate Zn6O(OH)(BO33 was prepared with industrial borax and zinc sulfate heptahydrate as raw materials by precipitation process.Structure and morphology of the product were characterized by means of X-ray powder diffraction(XRD),scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR),and thermo gravimetric analysis(TGA) etc.The influences of reaction pH,reaction temperature,reaction time,and mix ratio of reactants on the structure and composition of product were investigated.The conditions of synthesizing Zn6O(OH)(BO33 were obtained as follows: amount-of-substance ratio of industrial borax to zinc sulfate heptahydrate was 1∶1,reaction pH was at 7.5~8.0,reaction temperature was 90 ℃,and reaction time was 6 h.The yield of the product was 83% under those condtions.

Key words: zinc borate, precipitation process, process condition
