TITANIUM OXIDE-CONTAINING BOROSILICATE GLASS FREE FROM ARSENIC AND ANTIMONY AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide titanium oxide-containing borosilicate glass without using an arsenic compound and an antimony compound as a refining agent during manufacturing.

SOLUTION: There is provided the titanium oxide-containing borosilicate glass which is manufactured without using the arsenic compound and the antimony compound. There is also provided an environment-friendly refining method which includes a step for using an oxygen-containing selenium compound as a refining agent. Since the glass has a favorable transmittance value in the infrared range and does not show obstructive discoloration, it is especially suitable for manufacturing an IR photoconductor, cover glass for an optical sensor and a UV filter.
