Rutile Sand
Rutile Sand
The Rutile Sand is a heavy mineral sand, containing titanium with typical specifications: TiO2: 95% min/Fe2O3: 1% max/ZrO2: 1% max. Its appearance is black/brown in colour. The application is for TiO2 pigment, welding electrodes, titanium metal, ceramics and glass products colouring agents, filler in paints, etc. The grade and brand available are: premium grade 95% TiO2. It is a method of removing oxygen from a solid metal, metal compound or semi-metal M1O by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that reaction of oxygen rather than M2 deposition occurs at an electrode surface and that oxygen dissolves in the electrolyte M2Y and wherein, M1O is in the form of (sintered) granules or in the form of a powder which is continuously fed into the fused salt. Also disclosed is a method of producing a metal foam comprising with the steps of fabricating a foam-like metal oxide perform, removing oxygen from said foam structured metal oxide perform by electrolysis in a fused salt of M2Y or a mixture of salts, which comprises conducting electrolysis under conditions such that, reaction of oxygen rather than M2 deposition occurs at an electrode surface.
