Borosilicate glass Why add B2O3
Borosilicate glass, English called "borosilicate glass", the main component of alkali borosilicate glass (R2O-B2O5-SiO2) and non-alkali-low silicon borate glass (RO-B2O5-SiO2) glass, add Into the B2O3 borosilicate glass 5 aspects of the effect:
1, eliminate color, increase transparency and clarity.
Borosilicate glass due to the relatively high content of B2O3, B2O3 has a superior elimination of glass color difference effect, this has to eliminate the color of the glass, also known as white glass, which in the prism, the lens is actually a wide range of practical production process , An effective solution to the light diffuse reflection and light diffuse problem.
2, thermal stability, a wide range of applications.
Borosilicate glass is also known as heat-resistant glass, the thermal expansion coefficient is only 2/5 of ordinary glass, so in household appliances, environmental engineering, chemical engineering, lighting, precision machinery, bio-engineering, safety protection widely used The The
3, increase the resistance to reduce the occurrence of security incidents.
B2O3 in borosilicate glass can effectively increase the resistance of glass surface, the resistance value is 2-3 times the ordinary glass, the principle is that B2O3 to strengthen the formation of BO4 tetrahedral glass network structure, reducing the electric field Na ion movement.
4, slow down the Na ion changes, to ensure that the glass is inherently stable.
Ordinary soda lime glass in the high-frequency light irradiation can make the glass surface temperature rise, this is because in the high-frequency electromagnetic field, the glass body Na ion changes. The addition of B2O3 borosilicate glass, the Na ion can change the probability of reducing more than 60%, in the same working environment, the vitreous structure is more stable.
5, reduce the surface tension, put an end to the phenomenon of glass blew.

5, reduce the surface tension, put an end to the phenomenon of glass blew.
Borosilicate glass is replaced by B2O3 Na2O-SiO2 part of the SiO2, the glass surface tension can be greatly reduced, and the glass surface tension is reduced, it will put an end to the glass blew the occurrence, which is borosilicate glass Why more than the reasons for the use of soda lime glass.
