氧化鋁(lv)空心球(qiu)制品是采用氧化鋁(lv)空心球(qiu)為(wei)主要(yao)原料(liao)，高(gao)(gao)性能剛(gang)玉細粉為(wei)添加劑，成(cheng)型(xing)干燥后，在1750℃高(gao)(gao)溫(wen)(wen)窯爐中燒制而(er)成(cheng)。氧化鋁(lv)空心球(qiu)制品具有耐高(gao)(gao)溫(wen)(wen)，密度(du)小，導熱系數低，保溫(wen)(wen)性強，可以提高(gao)(gao)窯爐使(shi)用熱效率，減輕爐體重量，降低能耗。

氧化鋁空(kong)(kong)心球制品在(zai)航天、原(yuan)子(zi)能、電(dian)子(zi)工業和新能源等(deng)行業廣泛(fan)的(de)應用。與(yu)其它輕質隔熱材料(liao)相比，氧化物(wu)空(kong)(kong)心球磚隔熱材料(liao)的(de)特點是安全(quan)使用溫度(du)高(gao)、強度(du)大和熱導率小。他(ta)們的(de)體積(ji)密度(du)比同成分的(de)致密制品低50%~60%，可承受高(gao)溫火焰的(de)沖擊，直接作為高(gao)溫窯爐的(de)內襯(chen)。

Alumina hollow ball products are made by using alumina hollow ball as the main raw material, high-performance corundum fine powder as an additive, molding and drying, and firing in a 1750 ℃ high-temperature furnace. Alumina hollow ball products have high temperature resistance, low density, low thermal conductivity and strong thermal insulation, which can improve the thermal efficiency of the furnace, reduce the weight of the furnace and reduce energy consumption.

Alumina hollow ball products are widely used in aerospace, atomic energy, electronic industry, new energy and other industries. Compared with other lightweight insulation materials, oxide hollow spherical brick insulation materials are characterized by high safe use temperature, high strength and low thermal conductivity. Their bulk density is 50% ~ 60% lower than that of dense products of the same composition, which can withstand the impact of high-temperature flame and can be directly used as the lining of high-temperature kilns.
