玻化微珠是一种无机物玻璃质矿物材料，是由火山岩粉碎成矿砂，经过特殊膨化烧法加工而成，产品呈不规则球状体颗粒，内部为空腔结构，表面玻化封闭，理化性能稳定，具有质轻、隔热防火、耐高低温、抗老化、吸水率小等优良特性。可替代粉煤灰漂珠、玻璃漂珠、普通膨胀珍珠岩、聚苯颗粒等诸多传统轻质骨料在不同制品中的应用，是一种环保型高性能无机轻质绝热材料。玻化微珠的物理性能见表4。

玻化微珠作为建筑保温材料可以弥补用聚苯颗粒和普通膨胀珍珠岩作轻质骨料的其他传统保温材料中诸多缺陷和不足，可以克服膨胀珍珠岩吸水性大、易粉化、在搅拌中体积收失率大、产品后期保温性能降低和易空鼓开裂等不足之处，同时又弥补了聚苯颗粒有机材料易燃、防火性能差、高温产生有害气体和耐老化性耐候性低等缺陷。可广泛用于建筑节能、化工填料、科技农业、耐火材料和防火吸音等行业，后续的应用领域也十分广泛。
