Pyrolitic glass is glass used in ovens with pyrolitic function .This characteristics

of this glass is that it is more resistant thermal shocks in comparison with normal

glasses .At the moment borosilicate glass is used as pyrolitic glass .

Borosilicate glass is a type of glass of which the main ingredients for the

formation of glass are silica and boron axide.

Dihua s glass is a borosilicate glass type 3.3 as specified in international standard ISO ***5,whose chemical resistance of glass is more extensive than that of all other known materials.Borosilicate glass is highly resistant to water,acids,salt solutions,organic substances and also halogens such as chlorince and bromine.It also has relatively good resistance to alkaline solutions.Only hydrofluoric acid,concentrated phosphoric acid and strong alkaline solutions cause appreciable surface removal of the glass at higher temperature.This kind of glass is manufactured from natural raw materials(sand,calcium carbonate and sodium carbonate) and doesnt contain any materials which could be released and constitute a hazard to man or the environment .Glass can be reused several times and disposed of without difficulties.
