Abstract

The structure and properties of the glass can be modified by introducing appropriate additives. Dolomite is one of the primary raw materials modifying the properties of glass, in which the essential component is calcium-magnesium double carbonate CaCO∙MgCO. The paper presents the research results on glasses obtained by smelting pure amphibolite and amphibolite modified with 10 and 20% dolomite additives. The raw material used was mined in the Poland region of Lower Silesia. The glass melting process was carried out in an electric furnace at 1450 °C for 2 h. The structure and properties of the glasses and crystallization products were determined by Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). Viscosity and Vickers microhardness were also measured. It was found that the modification of amphibolite glass by adding dolomite affects the glasses' properties and structure. The research results determined the effect of dolomite addition on the properties of alumino-silicate glasses in terms of the mineral fibre products used in the construction industry.

摘要

通过引入适当的添加剂，可以改变玻璃的结构和性能。白云石是改变玻璃性能的主要原材料之一，其主要成分是碳酸钙镁复盐CaCO₃∙MgCO₃。本文介绍了通过熔炼纯角闪石以及添加10%和20%白云石添加剂改性的角闪石所获得玻璃的研究结果。所用原材料采自波兰下西里西亚地区。玻璃熔化过程在电炉中于1450℃下进行2小时。通过差示扫描量热法（DSC）、X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）和扫描电子显微镜-能谱仪（SEM-EDS）测定玻璃及结晶产物的结构和性能。还测量了粘度和维氏显微硬度。结果发现，添加白云石对角闪石玻璃进行改性会影响玻璃的性能和结构。研究结果确定了在建筑行业使用的矿物纤维产品方面，添加白云石对铝硅酸盐玻璃性能的影响。
