Abstract

Abstract

TiB₂ powders were synthesized in NaCl-KCl molten salt by amorphous boron and Ti-Si-Fe alloy extracted from high titanium blast furnace slag. The effects of reaction temperature, holding time, molten salt amount and mole ratio of B to Ti on the reaction process were investigated. The results show that increasing the reaction temperature or extending the holding time can promote the reaction process. TiB₂ begins to form at 850 ℃ and the reaction completes at 1 100 ℃. Molten salt can facilitate the reaction process. The distribution of elements shows that the particles containing Fe also contain Si, corresponding to the product FeSi₂. Most of the particles contain Si, Ti and B at the same time, indicating that TiB₂ and Si are associated in these particles. A few particles contain only Ti and B, corresponding to TiB₂. There are two kinds of particle morphology of the product. One kind of particle presents cracking appearance with cracks or micron holes connected to the interior, which contains TiB₂, Si or FeSi₂. The other particle is composed of flake TiB₂. The reaction mechanism of Ti-Si-Fe alloy with B in molten salt is described below. First of all, titanium reacts with B to form TiB₂ , then Si and FeSi₂ are released. Most TiB₂ nucleate and grow with Si and FeSi₂ as the skeleton which maintain the original morphology of Ti-Si-Fe particles. A small amount of TiB₂ nucleate and grow in molten salt to form flake TiB₂ aggregates. The sequence of reaction between alloy phase and B is Ti₅Si₃, TiSi, TiFeSi₂ and TiSi₂.
