高抗热震性氧化铝空心球砖的研制

Development of Alumina Bubble Brick with Good Thermal Shock Resistance

以氧化铝空心球为骨料，基质中加入适量的SiO2及硅线石，生产出了热震稳定性好、重烧线变化率小的氧化铝空心球砖。

Using alumina bubble as aggregate and adding an amount of silica and sillimanite in the matrix, an alumina bubble brick with good thermal shock resistance and low reheating linear change has been developed.
