Vanadium silicide

Volume III Halides, Hydroxides, Oxides. (1997) ISBN 0-9622097-2-4 (descriptions of 628 mineral species, including antimonates, antimonites, arsenites, carbides, halides, hydroxides, nitrides, oxides, phosphides, silicides, vanadium oxysalts). 

The silicides of major industrial importance are the disilicides of the refractory metals molybdenum, tantalum, titanium, tungsten, vanadium, and zirconium.pl] These compounds are of great interest par-... 

Aluminium-Silicon.—Vanadium possesses the property in common with a large number of other metals of forming complex alloys with aluminium and silicon.7 Several of these vanadium-aluminium-silicides, each possessing different crystalline form, have been obtained... 

Vanadium Subsilicide, V2Si, is obtained by fusing a mixture of vanadium trioxide, V2Os, and silicon, with the addition of either a large excess of vanadium or carbon or copper. The carbide or copper alloy produced is decomposed at the temperature employed.11 The silicide forms metallic prisms, of density 5-48 at 17° C., the m.pt. of which is higher than in the ease of the disilicide. It is attacked by the halogens, hydrogen chloride gas, and fused sodium or copper, but hydrochloric acid, nitric acid and sulphuric acid are without action.

Berzelius, Johnston and others tried in vain to isolate the metal itself. The substances they thought were metallic vanadium, obtained by reduction of vanadium oxide with carbon or potassium, or of vanadium chlorides (VCI3, VOCI3) with potassium or ammonia, all turned out to be carbides, silicides, nitrides (VN) or low-valent oxides (VO).[ l The first apparently successful generation of metallic vanadium was accomplished by Sir Henry Enfield Roscoe in 1869 by reduction of VCI2 with hydrogen in a lengthy experiment [ 1...

In February, 1980, Sumitomo from Japan filed the patent Sintered compact for a machining tool and a method of producing the compact [161]. This patent basically covers any compact with 10-80 vol% cBN and a balance of binder material that can comprise any carbides, nitrides, borides, or silicides of metals of groups IVa, Va, or Via. Specifically mentioned are titanium, zirconium, hafnium, vanadium, niobium.
