Ablaze Glass Works - What are the Physical Characteristics of Borosilicate Glass

1. What are the Physical Characteristics of Borosilicate Glass? Borosilicate glass is a type of glass that is mostly composed of silica and boron trioxide. Borosilicate glasses have much lower thermal expansion coefficients than most common glasses (≈3 × 10−6 K−1 at 20 °C), making them very resistant to thermal shocks. Such glass is less thermally strained and can withstand temperature fluctuations of up to 165 degrees Celsius (297 degrees Fahrenheit) without cracking. It's used to make reagent bottles and flasks, as well as lights, electronics, and cookery. If you are looking for the most popular and noted Glass valves manufacturer in Vadodara, Ablaze Glass Works is the name you can trust. Physical Characteristics: The most common variety of borosilicate glass used in laboratory glassware has a thermal expansion value of about one-third that of conventional soda-lime glass (3.3 × 10−6 K−1). Fused quartzware is even better in this sense, with one-fifth the thermal expansion of soda-lime glass; however, quartzware is much more expensive due to the difficulty of dealing with fused quartz, and borosilicate glass is a low-cost compromise.

2. Despite being more resistant to thermal shock than other varieties of glass, borosilicate glass can nevertheless crack or shatter when exposed to rapid or uneven temperature fluctuations. Ablaze Glass Works is an excellent and most recognised borosilicate glass manufacturer and supplier in Vadodara. Because to boron's low atomic mass, borosilicate glass is less dense than soda-lime glass (approximately 2.23 g/cm3). At constant pressure (20–100 °C), it has a specific heat capacity of 0.83 J/(g.K), which is around one-fifth that of water. Ablaze Glass Works is one of the most reliable and renowned borosilicate glass manufacturers in India. Before breaking, borosilicate glass can endure a temperature differential of around 330 °F (180 °C), but soda-lime glass can only withstand a temperature differential of around 100 °F (56 °C). This is why traditional soda-lime glass kitchenware will shatter when placed on ice with a boiling water pot, whereas Pyrex or any other borosilicate laboratory glass will not. Low dispersion (Abbe numbers about 65) and lower refractive indices (1.51–1.54 across the visible range) characterise borosililicate glasses.
