Abstract:
يتناول البحث امكانية استخدام الاطيان النهرية المحلية في انتاج انواع من الزجاج عالي الحرارة، وقد حددت طينة خان بني سعد النهرية الحمراء، اذ اخذت كمية من الطينة وتم غسلها وتنقيتها من الشوائب والرمال الخشنة بطريقة الترسيب، وحرقت بدرجة حرارة (700) ( كلسنة ) | The research the possibility of using arable land river local produce kinds of glass, high temperature, have been identified Tine Khan Bani Saad, the river red, where it has a quantity of this clay has been washed and cleaned of impurities and coarse sand in a deposition, and burned at a temperature (700) (calcinations) to get rid plasticity of clay and organic matter after what appeared a problem secede from the body layer of glaze pottery at the application stage of drought (before Firing). Were evaluated the results of initial trials by relying on chemical analysis has been attributed Tina to (Unity Formula) to find out the percentage of vehicles and determine the type of treatment, addition, and make up the shortfall, with a number of processors through the addition of materials used in the composition of glass as material modified the sand silicosis (Erdma ) and Kaalin Duejlh and feldspar Iraqi and feldspar Mxidized which was added in different proportions to the clay, and burned models with varying temperature of the three (1230 m - 1260 m - 1290 m), where the effect of oxides of coloring in the installation of clay and a clear transparent glass, and seemed colors green olive to the honey - colored and dark brown.Was conducted several tests on laboratory models of glass, the most important examination of hardness, abrasion resistance and testing, resistance to chemicals, metal detector. Found during the tests and experiments that the most important factors to form glass cooked at high temperatures of the clay used in the research was to balance the rates of oxides falling within the composition according to the law of the unity of the formula (Unity Formula), and found by experience that there is a difference in the fusion of materials and lack of homogeneity and their interaction enough at certain temperatures there is more than a glass phase in the liquid molten glass, and increased rates of added silica and alumina caused the increase of degrees of maturity and fusion, as well as high hardness of glass and its resistance to scratching and acids. As the examination (X.R.D) crystallization of new minerals after all components of the glass melting temperature specified in the search except the temperature of 1290 AD as any metal did not materialize because of a new high - temperature melting and destroying the Shabak and the full crystal glass.
