在理论计算的基础上,在实验室内分别研究了 B_2O_3及 B_2O_3和 TiO_2同时在铝电解槽中的热还原和电析出。在正常电解条件下,只要适当地控制电解质中 B_2O_3和 TiO_2的含量,不但可控制铝-硼合金中B 的含量及铝-钛-硼合金中 Ti 和 B 的含量,还可控制铝-钛-硼合金中 Ti 与 B 之比。这种合金可直接做铝及各种铝合金晶粒细化剂的中间合金。本文所研究的电解质体系与工业铝电解质成分和技术条件相似。研究结果对在工业电解槽中直接生产铝-硼及铝-钛-硼合金有着重要的参考价值。
On the basis of theoretical calculation, the thermal reduction and electrocatalysis of B_2O_3, B_2O_3 and TiO_2 simultaneously in aluminum reduction cell were studied in laboratory respectively. Under proper electrolysis conditions, the content of B 2 O 3 and TiO 2 in the electrolyte can be properly controlled not only to control the content of B in the aluminum-boron alloy and the content of Ti and B in the aluminum-titanium-boron alloy, but also to control the content of the aluminum- The ratio of Ti to B in boron alloys. This alloy can be directly made of aluminum and aluminum alloy grain refiner intermediate alloy. The electrolyte system studied in this paper is similar to industrial aluminum electrolyte composition and technical conditions. The results have important reference values for the direct production of aluminum-boron and aluminum-titanium-boron alloys in industrial electrolyzers.
