Abstract
The reaction zone formed between boron oxide B13O2 and liquid Al during 1 hour interaction at 1173 K and 1273 K was investigated using the optical, transmission electron microscopy and energy dispersive X-ray spectroscopy.
The structural examinations suggest the occurrence of oxy-redox reaction resulting in the formation of aluminium oxide precipitates and two types of aluminium borides identified as AlB2 and as either γ- or β-A1B12. The nearly continuous layer of coarse grains AlB12 phase is noted to occur in the drop side of the interface. The AlB12 crystallites are heavily faulted and contain numerous small inclusions of AlxOy or AlxOyBz type. The AlB2 needles are nucleated at the A1B 12 crystallites and extend into the aluminium drop. Below the AlB12 layer a much thicker region of reactive infiltration has been observed.
