Effect of HCl concentration on TiB2 separation from a self-propagating high-temperature synthesis (SHS) product

Preparation of single phase molybdenum boride

“…3b and d). Mg 3 B 2 O 6 forms by the reaction of MgO and B 2 O 3 and it is an undesired side product in the magnesiothermic production of borides due to the difficulty of removing it from the products by leaching [6,8,29]. It was previously found that 15 h was sufficient for removal of Mg 3 B 2 O 6 from VCS products by leaching in 1 M HCl [6].…”

“…Most of the studies have been focused on preparation of TiB 2 or TiB 2 containing composites [6][7][8][9][10][11][12]. Molybdenum borides have been used as hard coating materials for high temperature structural applications, and also in the form of MoB/CoCr cermet coatings [1,2,13].…”

Determination of the thermodynamic stability of TiB2

“…TiB 2 is a refractory intermetallic compound with high hardness, low density, high electrical conductivity, good thermal shock resistance, chemical inertness, excellent wear and corrosion resistance and high elastic modulus [1,2]. These properties render it suitable for many applications, such as in the manufacture of wear resistant parts, ballistic armour, cathodes and thermocouple sheaths, crucibles for molten metals, metal evaporation boats and cutting tools as well as in tribological applications [2][3][4][5][6][7].…”

The neutron absorption properties of 10 B coupled with the high temperature stability of TiB 2 (containing 10 B) makes it a candidate material for the manufacture of the control rods for fast breeder reactors [8][9][10].…”

Phase and morphology studies of B4C–SiC nanocomposite powder synthesized by MASHS method in B2O3, Mg, C and Si system

“…Acid leaching has been done to remove impurities. In many researches, acid leaching has been used by HCl at different concentrations and times to remove MgO and other undesirable products [1,2,8,15]. B 4 C-SiC composite has been prepared in several methods.…”
