Products Introduction

    It is well known that the defect in the glass structure can lead to "color center" under high irradiation. Irradiation-resistant dopant such as cerium can decrease the amount of the "color center". We prepared irradiation resistant glass by doping Irradiation-resistant dopant to Li₂O-Al₂O₃-SiO₂ system based glasses.
    Irradiation resistant glass can used as irradiation-resistant & irradiation-proof transparent materials, for example, cover glass in solar cell, CRT tube in aerospace or space fields. The glass has high strength, excellent corrosion-resistant, heat-stability and easy strengthened with ion-exchanging.
