Claims12
A method for manufacturing a glazed composite, the method comprising:
- grinding each raw material of a set of raw materials independently, wherein the set of raw materials comprises ceramic waste and colored glass waste;
- sieving each raw material of the set of raw materials independently to filter out particles having diameter more than about 90 microns;
- mixing the set of raw materials to obtain a homogenous mixture;
- sieving the homogenous mixture for filtering out particles having diameter more than about 90 microns;
- pressing the homogenous mixture admixed with water in response to sieving, wherein 1 ml of water is added per 10 g of the homogenous mixture;
- and
- firing the homogenous mixture at a temperature of about 700 degree C. (° C.) to 1200° C.
A composition of a glazed composite comprises about 62 wt % to about 90 wt % of silicon dioxide (SiO2), about 2 wt % to about 17 wt % of alumina (Al2O3), about 5 wt % to about 10 wt % of calcium oxide (CaO), about 2 wt % to about 14 wt % of sodium oxide (Na2O), about 2 wt % to about 4 wt % of potassium oxide (K2O), about 0. 5 wt % to about 1. 0 wt % of titanium dioxide (TiO2) and about 0.1 wt % to about 5 wt % of ferric oxide (Fe2O3).
