Removal technology of boron dissolved in aqueous
网页2014年3月5日Boron dissolves in aqueous solutions as various species on the basis of concentration. In high boron concentration aqueous, several boron species are found, such as B 2 O (OH) 62−, B 3 O 3 rings including B 3 O 3 (OH) 4−, B 4 O 5 (OH) 42−, and B 5

Behavior of Boron in Molten Aluminum and its Grain
网页2012年9月13日The experimental results showed that boron is dissolved in pure aluminum while its dissolution is inhibited in presence of titanium solute. A thin layer of TiB 2 formed at the surface of boron thickens with residence time in the melt. The mechanisms by which aluminum is crystallized on boron are discussed. 1 Introduction
