Abstract

The invention discloses a color adjusting method of lithium-containing manganese dioxide colored glass. The colored glass is prepared by using silicon oxide, calcium oxide, lithium oxide, manganese dioxide and sodium nitrate, and the color adjusting method is characterized in that the color of the glass is adjusted by adjusting the amount of lithium oxide within a range of 0-40% when the content of manganese dioxide is certain. A series of different colors of purple glass can be obtained by changing the content of lithium oxide without changing of the content of manganese, so same batch glass chromatic aberration caused by manganese valence change due to different atmospheres in the melting process is avoided, thereby the operation is simple; and the addition of sodium nitrate ensures the strong oxidizing property of the melting atmosphere, and guarantees the stability of the coloring effect.

Description

technical field [0001] The invention relates to colored glass in the field of inorganic non-metallic materials, in particular to a method for adjusting the color of lithium-containing manganese dioxide colored glass. Background technique [0002] In the existing colored glass, the manganese-containing glass is violet. Generally, it is necessary to change the manganese content in the glass ingredients to obtain different shades of purple glass, and because manganese has various valence states of +2~+7, the melting atmosphere is slightly different. Even if the manganese content is the same, the color of the glass obtained by melting will be different, and it is difficult to accurately control the color of the glass. Contents of the invention [0003] In order to solve the problem in the prior art that the color of manganese-containing colored glass changes uncontrollably with the melting atmosphere, the present invention provides a method for adjusting the color of lithium-c...
