1) alumina variety
氧化铝变体
2) alumina supporter
氧化铝载体，氧化铝架体
3) alumina support
氧化铝载体
1.
The alumina support was treated in the moderate aqueous hydrothermal condition to avoid from the excess growth of boehmite (AlOOH) crystals which usually results in the obvious decrease of the specific surface area (BET).
为制备高活性负载型催化剂,人们对氧化铝载体进行了大量的改性研究,如对前驱物进行热处理以增加其多孔性[2]、添加TiO2、B、F等制备复合载体提高其表面酸性[3~5]等。
4) alumina carrier
氧化铝载体
1.
The results indicated that nanoparticles alumina carrier had good stability,even distribution,large pore size,surface area and pore volume,high strength and lower bulk density,which conformed to characteristics of nanoparticles.
结果表明,制备的超增溶纳米自组装氧化铝载体性能稳定,分布均匀,具有较大的孔径、比表面积和孔容,强度高,堆积密度小,符合纳米粒子特性。
5) alumina powder
氧化铝粉体
1.
High-purity (>5N) aluminum alkoxide as precursor and alumina powders were prepared from lower purity (>99.
９９９%)铝醇盐为前驱物,采用Ｓｏｌ－Ｇｅｌ技术制备高纯超细氧化铝粉体。
