In the laboratory, a beaker was taken out of a 300 ℃ oven and directly immersed in ice water without any damage; In the kitchen, the glass teapot remains as smooth as new after countless boiling and steeping. Behind these miracles, they are all attributed to a magical material - borosilicate glass. So, what is the special feature of this glass that can easily cope with extreme temperature differences? Let's uncover its mysteries at the molecular level.
The secret weapon of molecular structure
The extraordinary nature of high borosilicate glass lies in its unique chemical composition. Compared with ordinary glass, it adds 12% -15% boron trioxide (B ₂ O3) on the basis of silicon dioxide (SiO ₂). This change forms a tighter three-dimensional network structure of silicon oxygen boron at the microscopic level, making the internal stress distribution of the material more uniform. Like a more elastic net, it can better absorb and disperse thermal stress during drastic temperature changes, avoiding local rupture.
Key breakthrough in thermal expansion coefficient
The thermal expansion coefficient of ordinary glass is about 9 × 10 ⁻⁶/℃, while high borosilicate glass is only 3.3 × 10 ⁻⁶/℃. This means that under the same temperature difference, the volume change of high borosilicate glass is less than one-third of that of ordinary glass. This characteristic allows it to withstand instantaneous temperature differences of up to 300 ℃, which is 3-5 times the limit that ordinary glass can withstand. Experimental data shows that a 2mm thick high borosilicate glass sheet can drop from 200 ℃ to 0 ℃ without breaking within 1 second.
The Application Revolution from Laboratory to Daily Life
This excellent temperature resistance enables high borosilicate glass to excel in multiple fields. In the field of scientific research, it has become the preferred material for chemical experimental vessels; In the medical industry, it is used to manufacture syringes that can be sterilized at high temperatures; In the home furnishing industry, make glass cookware that can be directly heated with an open flame. According to statistics, the breakage rate of experimental vessels using high borosilicate glass is reduced by more than 80% compared to ordinary glass, greatly improving experimental safety.
Temperature password for manufacturing process
The manufacturing process of high borosilicate glass is also full of technological content. The raw materials need to be melted at high temperatures above 1600 ℃, which is about 200 ℃ higher than ordinary glass. This high-temperature treatment allows boron atoms to fully integrate into the silicon oxygen network, forming a more stable structure. Modern technology also optimizes the internal stress distribution by precisely controlling the cooling rate, allowing the finished product to easily withstand the extreme test of "ice and fire".
From molecular structure to macroscopic properties, high borosilicate glass demonstrates the subtleties of materials science to us. It is not only a functional material, but also a wonderful presentation of human intelligence in the microscopic world. With the development of technology, this' temperature master 'will undoubtedly demonstrate its unique value in more fields.
