氧化鋁(lv)空(kong)心球(qiu)(qiu)(qiu)制(zhi)(zhi)品是(shi)采(cai)用氧化鋁(lv)空(kong)心球(qiu)(qiu)(qiu)為主要(yao)原料，高性能(neng)剛(gang)玉(yu)細粉為添加劑，成型干(gan)燥后，在1750℃高溫窯(yao)爐(lu)中燒制(zhi)(zhi)而成。氧化鋁(lv)空(kong)心球(qiu)(qiu)(qiu)制(zhi)(zhi)品具有耐高溫，密(mi)度小，導熱(re)(re)系數低，保溫性強(qiang)，可以提高窯(yao)爐(lu)使用熱(re)(re)效(xiao)率(lv)，減輕爐(lu)體重量，降(jiang)低能(neng)耗(hao)。

氧(yang)化鋁空心(xin)球制(zhi)品在航天、原子能(neng)、電子工業和新能(neng)源等行業廣泛的(de)應(ying)用。與其(qi)它輕質隔熱材料相比，氧(yang)化物空心(xin)球磚隔熱材料的(de)特點是安全使用溫度(du)高(gao)(gao)、強度(du)大和熱導(dao)率小。他們(men)的(de)體積密(mi)度(du)比同成分的(de)致(zhi)密(mi)制(zhi)品低(di)50%~60%，可(ke)承受高(gao)(gao)溫火焰的(de)沖(chong)擊，直接作為高(gao)(gao)溫窯爐(lu)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.
