Abstract
Disclosed is soda-lime-silica glass doped with radiation shielding nano-sized samarium oxide (Sm2O3), which provides a transparent appearance in different areas where radiation-induced ionizing rays will occur, especially in medical diagnostic centers and research institutes, and can also be used to prevent harmful radiation-induced ionizing rays.
Claims11
A radiation shielding soda-lime-silica glass that allows a transparent appearance in different areas where radiation-induced ionizing rays will occur, especially in medical diagnostic centers and research institutes, and at the same time can be used to prevent harmful emissions from radiation, the radiation shielding soda-lime-silica glass comprising SiO2, Na2O, CaO, MgO, Al2O3, Fe2O3 and nano-sized Sm2O3 dopants.
A radiation shielding soda-lime-silica glass material production method comprising the following process steps:
- i. preparation of a raw material composition prescription,
- ii. weighing and grinding of Silica, Lime and Soda starting raw materials according to the prescription,
- iii. obtaining nano-sized Sm2O3 powder by calcination of Sm2O3 powder obtained by combustion synthesis,
- iv. mixing of the ground soda-lime-silica raw materials and nano-sized Sm2O3 powder with a mill and/or a mechanical mixer until a homogeneous mixture is formed,
- v. melting the mixture in a melting furnace at a temperature between 850 and 1200° C.,
- vi. transferring the molten glass into the forming mold and keeping it at room temperature,
- vii. annealing of the final shaped glass products in an annealing furnace at temperatures between 40° and 700° C. to remove internal stresses.
