Borosilicate 3.3 serves as a material of truly functional and wide applications:
1).  Household electrical appliance (panel for oven and fireplace, microwave tray etc.);
2).  Environmental engineering and chemical engineering (Lining layer of repellence, autoclave  of chemical reaction and safety spectacles);
3). Lighting (spotlight and protective glass for jumbo power of floodlight);
4). Power regeneration by solar energy (solar cell base plate);
5). Fine instruments (optical filter);
6). Semi-conductor technology (LCD disc, display glass);
7). Iatrology and bio-engineering;
8). Safety protection (bullet proofglass)
