General description
在高温下二元M-Al（M = Fe、Ni或Co）合金表面形成α-Al2O3 保护膜的机理已有研究。具有不同酸度和水浓度（具有Brockmann活性I-V）的活化氧化铝可以很容易地对土壤中存在的氧化铝上的各种类型的水（即游离水、孔隙水和结合水）进行检测。
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.
Application
氧化铝（中性）已用于制备氧化铝负载的银（Ag/Al2O3）催化剂，其适用于通过烃（HC-SCR）选择性催化，对氮氧化物（NOx）进行还原。
氧化铝（氧化铝，Al2O3）已被用于制备多壁碳纳米管（MWCNT）阵列（由与纳米SiOx微粒结合的Fe纳米粒子组成）的一步自组装双螺旋。
Packaging
Brockmann氧化铝适用于柱色谱和吸附过滤。
