氧(yang)(yang)化鋁(lv)空(kong)心(xin)球(qiu)制品是采用氧(yang)(yang)化鋁(lv)空(kong)心(xin)球(qiu)為(wei)(wei)主要原料，高(gao)(gao)性能剛玉細粉為(wei)(wei)添加劑(ji)，成(cheng)型干燥(zao)后，在1750℃高(gao)(gao)溫窯爐中燒制而成(cheng)。氧(yang)(yang)化鋁(lv)空(kong)心(xin)球(qiu)制品具有耐高(gao)(gao)溫，密度小，導(dao)熱系數低，保溫性強，可以提高(gao)(gao)窯爐使用熱效(xiao)率，減輕爐體(ti)重量，降(jiang)低能耗。

氧化鋁空心(xin)球(qiu)制品(pin)在航天、原子能、電子工業和新能源等行業廣泛的(de)(de)應用。與其它(ta)輕質隔(ge)熱材(cai)料相比(bi)，氧化物空心(xin)球(qiu)磚隔(ge)熱材(cai)料的(de)(de)特(te)點(dian)是(shi)安(an)全使用溫(wen)度高、強度大和熱導率小。他們(men)的(de)(de)體積密度比(bi)同(tong)成分的(de)(de)致密制品(pin)低(di)50%~60%，可承(cheng)受(shou)高溫(wen)火焰的(de)(de)沖擊，直接作為高溫(wen)窯爐的(de)(de)內襯。

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.
