氧化(hua)鋁(lv)空(kong)心(xin)(xin)球制品是采用氧化(hua)鋁(lv)空(kong)心(xin)(xin)球為主(zhu)要原料，高(gao)(gao)性(xing)能(neng)剛玉細粉(fen)為添加(jia)劑(ji)，成型干燥后，在(zai)1750℃高(gao)(gao)溫窯爐(lu)中燒制而成。氧化(hua)鋁(lv)空(kong)心(xin)(xin)球制品具有耐高(gao)(gao)溫，密度小，導熱系數低(di)，保溫性(xing)強(qiang)，可以提高(gao)(gao)窯爐(lu)使用熱效率，減輕爐(lu)體重量，降低(di)能(neng)耗。

氧化鋁空心球(qiu)制(zhi)品(pin)在(zai)航天、原子(zi)能、電子(zi)工業和新能源(yuan)等(deng)行業廣泛的(de)(de)(de)(de)應用(yong)。與其(qi)它(ta)輕質(zhi)隔熱材(cai)料(liao)相比，氧化物空心球(qiu)磚(zhuan)隔熱材(cai)料(liao)的(de)(de)(de)(de)特點是安全使用(yong)溫度高(gao)、強度大和熱導率小。他們的(de)(de)(de)(de)體(ti)積密(mi)度比同成分的(de)(de)(de)(de)致密(mi)制(zhi)品(pin)低50%~60%，可(ke)承受高(gao)溫火焰的(de)(de)(de)(de)沖(chong)擊，直接(jie)作為高(gao)溫窯爐的(de)(de)(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.
