    *珠是一种能浮于水面的粉煤灰空心球，呈灰白色，壁薄中空，颗粒细、重量轻，高强*、表面封闭而光滑，热导率小，耐火度高、保温绝缘、应力应变均匀等多种功能，广泛用于耐火、保温材料的生产和在塑料、涂料、油漆油墨、陶瓷、封装材料、地板胶、石油钻探等领域作增强性填充料。能既有效地****产品性能或施工效果，又明显地降低生产成本，现已广泛应用于耐火材料的原料之中。
 
【*珠特性】
 
     1、高耐火度：*珠的主要化学成分为*的氧化物，其中二氧化硅（SiO2)约为50-65%，三氧化二铝(Al2O3)约为25-35%。因为二氧化硅（SiO2)的溶点高达1725摄氏度，三氧化二铝(Al2O3)的溶点为2050摄氏度，均为高耐火物质。因此，*珠具有****高的耐火度，一般达1600-1700摄氏度，使其成为优异的*耐火材料。
 
     2、质轻、保温隔热：*珠壁薄中空，空腔内为半真空，只有****微量的气体(N2、H2及CO2等)，热传导****慢****微。所以*珠不但质轻(容重250-450kg/m3)，而且保温隔热优异(导热系数常温0.08-0.1)，这为其在轻质保温隔热材料领域大显身手奠定了基础。
 
     3、硬度大、强度高：由于*珠是以*氧化物矿物相(石英和莫来石)形成的坚硬玻璃体，硬度可达莫氏6-7级，静压强度高达70-140MPa，真密度2.10-2.20g/cm3，因此，*珠具有很高的强度。一般轻质多孔或中空材料如珍珠岩、沸岩、硅藻土、*、膨胀蛭石等均是硬度差、强度差，用其制的保温隔热制品或轻质耐火制品，都有强度差的缺点。他们的短处恰恰是*珠的长处，所以*珠就更有竞争优势，用途更广。e p*ement materials, roof waterproof thermal insulation coating, road engineering, modified asphalt, etc.
