當(dāng)玻璃窯用粘土磚在高溫下與玻璃液接觸時(shí),最初是磚體表面被熔融玻璃所浸潤。此后,由于毛細(xì)管的作用,熔融玻璃被吸入磚的氣孔之中,熔融體中富含堿金屬的離子就會(huì)向氣孔周圍熟料晶相的間隙中逐步擴(kuò)散,交代反應(yīng)于是發(fā)生。玻璃液首先溶···

燒結(jié)AZS磚是以鋯英石和氧化鋁為主要原料,采用預(yù)合成料為骨料制成的制品。由于坯料為瘠性物料,僅依靠提高成型壓力提高耐火磚密度效果不佳,大型制品壓制增加次數(shù)還會(huì)導(dǎo)致層裂與密度不均的現(xiàn)象,需采取調(diào)節(jié)臨界粒度組成、加入復(fù)合結(jié)合···
