摘　　要：空心玻璃微珠作为一种新型球形玻璃质功能材料,在众多领域具有广阔的应用前景。以废玻璃粉为原料,采用喷雾干燥-火焰烧结法并通过对配方和空心化工艺设计得到3种配方的空心微珠,其相应的强度为5.34,7.50和6.26 MPa。通过对微珠的理化性质、形貌、尺寸和结构进行分析,发现微珠本身化学组成、粒径分布及烧结温度对强度都有不同程度的影响。当烧结温度为900℃,加入硫酸镁,粒径分布范围在20~100μm时,空心微珠的真密度为0.94g/cm^3,抗压强度为8.03 MPa。As a new type of spherical glass functional material, hollow glass microspheres have broad application potential in many fields. In this paper, three kinds of hollow microspheres were obtained by spray drying-flame sintering method using waste flat glass as raw material and their corresponding strength were 5.34, 7.50 and 6.26 MPa, respectively.The physical and chemical properties, morphology, size and structure of the microspheres were analysed. It was found that the chemical compositions, particle size distribution and sintering temperatures of the microspheres had different effects on the strength of the microspheres.When sintering temperature was 900 ℃ and magnesium sulphate was added, the true density and the compressive strength of hollow glass microspheres were 0.94 g/cm^3 and 8.03 MPa, respectively.
