Embodiment Construction
[0006] The composition of the glass-ceramic is SiO by weight percentage 2 45%, Al 2 o 3 10%, CaO 20%, MgO 6%, Na 2 O 3%, K 2 O 3%, BaO 2%, ZnO 7%, plus As 2 o 3 0.5%, colorant 3.5%. The coloring agent adopts copper oxide, nickel oxide, cobalt oxide, iron oxide, titanium oxide, cerium oxide, chromium oxide and the like. The various raw materials of quartz, feldspar, calcium carbonate, barium carbonate, zinc oxide, sodium nitrate, sodium carbonate, magnesium carbonate or magnesium oxide, arsenic trioxide and colorants that meet the above ingredients and have a fineness of less than 0.8mm are weighed in proportion Heavy, mixed and melted in a glass melting furnace, the melting temperature is 1320-1520°C. The molten liquid is quenched in water, dried and broken to obtain glass-ceramic granules for building decoration in colors such as white, yellow, red, blue, green and black passing through an 8-mesh sieve.
