Ordinary glass and high borosilicate glass: an in-depth dialogue of materials

Ordinary glass and high borosilicate glass are two widely-used types of glass materials in daily life and industrial production, though there are distinct differences between them in terms of raw material composition, cold and thermal impact resistance, useability and many other aspects. We will now examine some secrets related to these two varieties of glass.

At first glance, ordinary glass is mostly composed of silica while high borosilicate glass is composed of silica mixed with boron trioxide and other raw materials, giving high borosilicate glass an advantage in performance due to the addition of boron trioxide which reduces its thermal expansion coefficient by one third as compared with ordinary glass; when temperatures change suddenly or abruptly this means high borosilicate can better resist thermal stress, reduce temperature gradient stress effects, and thus provide stronger fracture resistance than ordinary glass does.

Second, the thermal shock resistance of both types of glass is a major difference. High-borosilicate has a smaller coefficient of thermal contraction, which makes it more stable when exposed to cold and hot shocks. Normal glass, on the other hand, is more likely than not to crack in a hot-cold environment. High borosilicate is therefore the best choice for environments that experience large temperature fluctuations.

High borosilicate has many other characteristics in addition to those mentioned above. Its shape deviation is small. Even when it breaks, the glass will not break into tiny particles but instead show large cracks. High borosilicate glasses are therefore more safe. High borosilicate glasses also have low dispersion, and a relatively low refractive indices, making them suitable for a variety of optical applications.

We must mention the high borosilicate products of IDEA. IDEA, a company that focuses on the production and development of high quality glass products has created a number of high borosilicate products of excellent quality with a strict system of quality control and advanced production technology. These products are not only high-quality, heat resistant, and transparent, but they also have a beautiful design, and many different functions that can meet the demands of customers.
