- Silica-alumina is
also known as alumino-silicate(s). It is an oxide-like combination of
aluminium, silicon and oxygen, and it has a major component of kaolin
and clays.
- Inorganic Chemistry
by Swaddle calls the group of minerals aluminosilicate when some of the
Si4+ ions in silicates are replaced by Al3+ ions. For each Si4+ ion
replaced by an Al3+, the charge must be balanced by having other
positive ions such as Na+, K+, and Ca2+ ions. Feldspar group and
zeolites are typical aluminosilicates by this definition.
- There are hundreds
of aluminosilicate minerals including the micas which form flat sheets.
A local variety of mica is biotite, K3AlSi3O10(OH)2. Another
aluminosilicate mineral, kyanite, Al2SiO5, forms long, fibrous crystals
and is mined locally at Willis Mountain. Feldspars are a broad class of
aluminosilicates, of which microcline, K[AlSi3O8], is a local variety.
Finally, Kaolinite, Al2Si2O5(OH)4, is an aluminosilicate mineral which,
when powdered and mixed with water, form one variety of clay.
- When amorphous
silica-alumina is treated with strong acids such as hydrochloric and
hydrofluoric acids, the material acts as a solid acid and becomes
capable to promote reactions that require acid catalysis. Under other
circumstances, when trivalent aluminum is forced by surrounding
tetravalent silicon to crystallize in a tetrahedral symmetry, a partial
electron deficiency occurs at the aluminum site allowing it to act as a
Lewis acid, or to react with a water molecule and form a conjugated
Brønsted. Natural and synthetic zeolites can be such crystalline
alumino-silicates if aluminum precursors are added in the synthesis
process.
- The major raw
materials required for the proposed unit are Sodium Silicate and
Aluminium Sulphate.
- The manufacturing
process involves preparation of Sodium Silicate Solution and reaction
with aluminium sulphate at predetermined temperature. Resultant slurry
is pumped into the filter press. The product after filteration is dried
and packed.
- Aluminium Silicate
is used as a filler and extender in the rubber, paper, paint and tooth
paste industries. It replaces the use of siliceous chemicals viz.
precipitated silica, hydrated calcium silicate, magnesium trisilicate
etc.
- Zeolites are a well
defined class of crystalline aluminosilicate mineral. They occur
naturally but also more than 150 types have been synthesised. In the
seventies Zeolite A was developed as a detergent builder. Builders are
ingredients which perform a number of functions in laundry detergents.
The most important one is to soften the wash water by complexing the
calcium and magnesium ions.
- Natural zeolites are
mainly used in building (cements) or in paper industry (fillers for
paper). Other applications of these materials are as cat litter, sewage
water treatment and in agriculture.
- The US market for
zeolites is valued at US$0.9billion. Catalysts are the biggest sector
representing two-thirds of demand and growing at 2 per cent per year.
Synthetic represent about one-third with a current growth of 4 per cent
per year. A small but fast growing sector is for use in pet litter
growing at 10 per cent per year to reach $8m.
- Investment of
about 30 Lakhs are required to put up a factory to produce 225 tonnes
per annum
