氧(yang)化鋁空(kong)(kong)心(xin)球制(zhi)(zhi)品(pin)是采用氧(yang)化鋁空(kong)(kong)心(xin)球為(wei)主要原料(liao)，高(gao)性(xing)能剛玉細粉為(wei)添加劑(ji)，成型干燥后，在1750℃高(gao)溫窯爐中燒制(zhi)(zhi)而成。氧(yang)化鋁空(kong)(kong)心(xin)球制(zhi)(zhi)品(pin)具有耐高(gao)溫，密度(du)小，導熱(re)系數低(di)，保溫性(xing)強，可以提高(gao)窯爐使用熱(re)效(xiao)率，減輕爐體(ti)重量，降低(di)能耗。

氧化鋁(lv)空心(xin)球(qiu)(qiu)制(zhi)品在航天、原子能、電子工業和新(xin)能源等行業廣泛的應用。與其它(ta)輕質(zhi)隔熱(re)材料相比，氧化物(wu)空心(xin)球(qiu)(qiu)磚隔熱(re)材料的特點是安(an)全使用溫度高、強度大和熱(re)導率小。他們的體(ti)積密度比同成分的致密制(zhi)品低50%~60%，可承(cheng)受高溫火焰(yan)的沖擊，直接(jie)作為高溫窯爐(lu)的內襯。

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.
