Title
(EN) NITRATE/NITRITE-FREE MANUFACTURING OF GLASS WITH SELENIUM
(ES) FABRICACION DE VIDRIO CON SELENIO SIN NITRATO/NITRITO
Abstract
(EN) The invention is a method of retaining selenium in a glass containing selenium by including a manganese compound but excluding nitrates or nitrites routinely used in the industry to retain selenium. Particularly, a preferred embodiment involves manufacturing a grey soda-lime-silica glass composition including selenium as a colorant, the components of the grey soda-lime-silica glass have colorants consisting essentially of:greater than 0.9 to 1.9 wt.%total iron oxide as Fe2O3;0.10 to 1.00 wt.%manganese compound as MnO2;0.0010 to 0.0060 wt.%selenium as Se;0.002 to 0.025 wt.%cobalt oxide as Co, and 0 to 1.0 wt.%titanium oxide as TiO2 which are combined and melted to make the glass composition. The glass composition has at 4.0 mm. thickness:10 to 55%light transmittance using Illuminant A, less than 25%ultra violet transmittance, and less than 50%infrared transmittance.
(ES) La invención es un método para retener selenio en un vidrio que contiene selenio incluyendo un compuesto de manganeso pero excluyendo los nitrato o nitritos comúnmente utilizados en la industria para retener el selenio. Específicamente, una modalidad preferida incluye la fabricación de una composición de vidrio gris de sílice de sosa y cal incluyendo selenio como colorante, los componentes del vidrio gris de sílice de sosa y cal tienen colorantes que consisten principalmente en:más que 0.9 a 1.9%en peso delóxido de hierro total como Fe2O3;0.10 a 1.0%en peso del compuesto de manganeso como MnO2;0.0010 a 0.0060%en peso de selenio como Se, 0.002 a 0.025%en peso deóxido de cobalto como Co y 0 a 1.0%en peso deóxido de titanio como TiO2. los cuales se combinan y funden para elaborar la composición de vidrio. La composición de vidrio tiene cuando menos 4.0 mm un espesor:10 a 55%de transmitancia de luz utilizando Iluminant A menos que 25%de transmitancia del ultra violeta y meno s que el 50%de transmitancia del infrarrojo.
