إنتاج زجاج الخزف الجاهز باستخدام مخلفات النباتات (قصب البردي)‎

الملخص EN

In this research, unconventional glaze mixture was used, depending on the product of burning papyrus cane (ash), on two burners, as explained in the research procedures, it was found that papyrus cane ash is a primary source of silica minerals (SiO2) with a percentage of (56.1%) as the main component of the porcelain glaze mixture, as well as alumina (Al2O3) and by weight (1.2%), as shown through the chemical analysis of this substance, and this was proven in table (2-3) of the research procedures, and this means double use of a substance considered as a residue (sedge cane) in the production of glaze and as a cleaning the environment from this material, and (5) glaze mixtures were prepared in which the weight ratios added to three oxides varied, they are (sodium oxide Na2CO3) and (potassium feldspar oxide K2O.

Al2O3.

6SiO2) and (boric oxide B2O3), then those mixtures were frit it separately at a temperature of (1200c˚) to improve the specifications of the glaze mixture, then the burning program was determined, scratch resistance and hardness tests were conducted, and the surface tensile coefficient, density, transparency and opacity of the glaze mixtures were calculated as shown in the research procedures and review of the results.
