Abstract
Borosilicate glass consists of an adjuvant such as silicon oxide, boron oxide and sodium oxide, which is mixed evenly and fused at 1700 degrees
Celsius. Finally, it is formed by a pipe drawing machine and cooled in an annealing furnace. The high performance of this kind of glass and a variety of processing and forming methods are the focus of this poster, which naturally corresponds to its unprecedented properties as glasses and other utensils. Compared with ordinary glass, borosilicate glass is superior in thermal, optical, mechanical and chemical properties. This poster provides the audience with information on the main characteristics and processing methods of borosilicate glass.
Introduction
· Amorphous solid mixture

· Good heat resistance, · High coefficient of thermal expansion
· Low specific gravity and Good optical properties
· A variety of manufacturing processing and forming method
Literature review
History
1900 Scientists set out to make highly heat
resistant glass.
1912 German chemists Otto Schott and
Ernst Abbe and physicist Carl Zeiss co-founded
a glass manufacturing company in Jena.
1950s Borosilicate glass has been used to
make reactor vessels with good results.
Today Widely used in optics, electronics,
aerospace, life science and many other fields.
Melting process
Combination of blow molding and casting
step 1 step 2 step 3 step 4 step 5 step 6
Method overview
- Step 1: Silicate and borate mixed evenly melt
- Step 2: Cool quickly after injection into the mold
- Step 3: Remove the finished product from the mold
The finished product produced by sol-gel method can be used in the production of optical devices because the internal phase will be more uniform after the solution step. optical devices. The finished products produced by melting can have different shapes according to different molds, and the process is simple and the molding effect is good. It is often used to produce utensils.
