| Abstract |
| Physicochemical characteristics of Phosphatic Slag from
a phosphorus manufacturing plant in Bhavnagar in
Gujarat State were studied with the object of determining
its suitability in the manufacture of low cost industrial
ceramic products like wall tile, L T insulators, crockery and
novelty wares as well as opaque glazes. The results showed
that the phosphatic slag is a solid solution of calcium silicate
and fluoride containing calcium oxide and silica as
major constituents but associated with impurities like sulphur
trioxide, fluorine, phosphorous pentoxide, alumina
etc. The study also revealed that the material could be used
as substitute of calcium and silica bearing materials like
calcite, wollastonite etc, up to 18.5 wt% in opaque glazes,
about 10 wt% in crockery and novelty wares and up to 30
wt% in earthenware wall tile bodies. The products developed
also conformed to the respective BIS Specifications as
required for commercial utilisation. |
