TiB₂ samples were exposed to molten KF−AlF₃−Al₂O₃: 54.8-42.1-3.1 mol% salt, at 680 °C for 50, 100 and 200 h. The corroded samples of TiB₂ were investigated by SEM-EDX, EBSD, XRD, FT-IR and MAS NMR analysis. Corrosion was noted to occur predominantly as pitting attacks on the surface of the investigated materials. An inter-crystal and trans-crystal corrosion were identified on the cross-sections of the samples. A perturbation of TiB bonds was detected (SEM-EDX and NMR analysis), at which a formation of orthorhombic TiO₂ was also identified (EBSD analysis). The subsequent NMR, XRD and FT-IR analysis of the behaviour of TiB₂ powder in molten KF−AlF₃−Al₂O₃ supports the statement about the formation of orthorhombic TiO₂ and mullite type of aluminium borates.

将TiB ₂样品在680°C下暴露于熔融的KF-AlF ₃ -Al ₂ O ₃：54.8-42.1-3.1 mol％的盐中50、100和200 h。通过SEM-EDX，EBSD，XRD，FT-IR和MAS NMR分析研究了TiB ₂腐蚀的样品。注意到腐蚀主要发生在被调查材料表面的点蚀。在样品的横截面上鉴定出晶间和跨晶腐蚀。检测到Ti B键的扰动（SEM-EDX和NMR分析），在该处还确定了正交晶TiO ₂的形成（EBSD分析）。随后的TiB ₂行为的NMR，XRD和FT-IR分析熔融KF-AlF ₃ -Al ₂ O _3中的粉末支持有关正交晶TiO ₂和莫来石型硼酸铝形成的陈述。
