what is the composition of glass describe in details different types of glass used for making of container
Answers
Answer:
Glass is an inorganic solid material that is usually transparent or translucent as well as hard, brittle, and impervious to the natural elements.
Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. Firstly the glass was manufactured in Egypt. Ordinary glass is manufactured by the composition of various substances like silica, bleaching powder, oxides of alkaline metals, calcium oxide (lime) etc.
Commercial glass is usually made of sand, limestone, and sodium carbonate that is raised in temperature until it is molten. It is then cooled quickly so as to prevent the formation of visible crystals.
Glass containers are among the primary packaging material that has found use in the pharmaceutical industries. A large number of pharmaceutical formulations have been packaged using glass containers glass containers and they are usually the first choice of packaging materials.
Glass is principally made up of silica (59-80%) with varying degree of calcium oxide (5-12 %) sodium oxide (12-17 %) aluminium oxide (0.5-3.0 %), barium oxide, boric oxide, potassium oxide, and magnesium oxide. The high melting point of glass is due to the presence of silica. The melting point and melt viscosity of the glass is modified by the addition of oxides.
