氧化(hua)鋁(lv)空(kong)心球(qiu)制(zhi)品(pin)是(shi)采用氧化(hua)鋁(lv)空(kong)心球(qiu)為主(zhu)要原料，高性能剛玉(yu)細(xi)粉為添(tian)加劑(ji)，成型干燥后，在1750℃高溫窯爐中燒制(zhi)而成。氧化(hua)鋁(lv)空(kong)心球(qiu)制(zhi)品(pin)具有耐高溫，密度小，導熱系數(shu)低，保溫性強，可以提高窯爐使用熱效率，減輕爐體重量，降低能耗(hao)。

氧化鋁(lv)空心球制品(pin)在航(hang)天、原子(zi)能、電子(zi)工業(ye)和新能源(yuan)等(deng)行業(ye)廣泛的(de)應用(yong)。與(yu)其它(ta)輕質隔(ge)熱(re)(re)材料相比，氧化物(wu)空心球磚(zhuan)隔(ge)熱(re)(re)材料的(de)特點是(shi)安全使(shi)用(yong)溫度(du)(du)高(gao)(gao)、強(qiang)度(du)(du)大和熱(re)(re)導率小。他們的(de)體積密(mi)度(du)(du)比同成分的(de)致密(mi)制品(pin)低50%~60%，可承受高(gao)(gao)溫火焰的(de)沖擊，直接作(zuo)為高(gao)(gao)溫窯爐的(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.
