1.Shirye-shiryen finafinan siliki na bakin ciki. Matakan siliki na sihiri tare da kyawawan halaye ana iya hada su kai tsaye ta hanyar dasa ions ƙarfe na vanadium tare da ƙimar katako mai girma. Tare da karuwar yawaitar katangar, lokacin sinadarin sinadarin vanadium yana tsirowa, kuma juriya ta takardar Rs na sikari na sihiri yana raguwa a bayyane. Lokacin da katuwar katako ya kasance 25 μ A / cm2, RS ya kai mafi ƙarancin darajar 22 of, wanda ke nuna cewa an ci gaba da yin ƙarar siliki. Binciken rarrabuwa na X-ray ya nuna cewa nau'ikan sinadarin vanadium guda hudu, gami da V3Si, V5Si3, V3Si5 da VSi2, an kirkiresu ne a cikin shimfidar da aka dasa. Bayan annan, RS ya ragu a bayyane, za a iya rage mafi ƙarancin rs zuwa 9 ψ, kuma juriya na iya zama ƙasa da 72 μ ψ m, wanda ke nuna cewa an ƙara inganta ingancin silinda mai ƙarancin siladium. Bayan allura mai tsayi da yawa da sanya ruwa, yanayin silicide na vanadium yana kara girma. Babban allurar ƙirar katako da haɗarin zafin jiki mai zafi (1200 ℃).

2. Sinadarin sinadarin Vanadium wani nau'in sauti ne mai daukar kayan yumbu. Launin farfajiya tare da dukiya mai ɗaukar sauti yana da rufi a saman layin tushe.
