BOROSILICATE FLOAT GLASS DESCRIPTION
Borosilicate
glass has a very low thermal expansion coefficient, about one-third
that of ordinary glass. This reduces material stresses caused by
temperature gradients, thus making it more resistant to breaking. This
makes it a popular material for objects like telescope mirrors, where it
is essential to have very little deviation in shape. It is also used in
the processing of high-level nuclear waste, where the waste is
immobilised in the glass through a process known as vitrification
(contrast with Synroc).
BOROSILICATE FLOAT GLASS 3.3 / BOROSILICATE FLOAT GLASS 4.0
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;
