Elvan glass compositions and glass products having far-infrared radiation and surface hydrophilic functions

摘要

The present invention relates to a ganbanite glass composition composed of naturally occurring quartz-feldspar bedrock, banbanite and a conventional soda-lime glass raw material, and to banban glass products having far-infrared radiation and surface hydrophilic functions prepared from the glass composition. The glass composition according to the invention comprises SiO ₂ , Al ₂ O ₃ , R ₂ O, wherein R ₂ O comprises at least one component selected from the group consisting of Na ₂ O and K ₂ O and RO (where , RO comprises at least one component selected from the group consisting of CaO and MgO) 50 to 99% by weight of the known soda-lime glass composition, and 1 to 50% by weight of the elvan powder The glass article according to the present invention is characterized in that it is prepared from the glass composition according to the present invention.
