The Difference Betwween  Borosilicate Glass And Ordinary Glass

Borosilicate heat-resistant glass belongs to a kind of "ripe glass", which is quite expensive and fully meets the international environmental protection inspection standard. Due to its heat resistance and resistance moment performance requirements of the temperature difference, high borosilicate material to replace the "glass" in a large amount of harmful heavy metals such as lead, zinc ion composition, so its brittleness and weight is far less than the life of the common normal "glass", and to ensure the rapid temperature change in an instant case will not happen burst phenomenon, its compared to contains a lot of heavy metal ions on the weight of the raw glass is much lighter, there are differences in appearance looks like common glass, the vision from the "glass" the feeling of hard and brittle.

1. Raw material composition: high borosilicate glass contains boron trioxide and silicon dioxide, and ordinary glass is relatively high, with boron content reaching 14% and silicon content reaching 80%. Plain glass contains about 70 percent more silicon. Plain glass is generally free of boron, but sometimes up to 1 percent more

2. Glass features: brosilicate glass has low expansion coefficient, high softening point and good quenching and heating resistance. Its expansion coefficient is about 32~33*10 (-7), and ordinary glass is about 80-100*10 (-7). Rapid cooling and rapid heat resistance can reach about 200~300 degrees Celsius.

The difference is to use fire, ordinary glass burned a point will soon break, high borosilicate glass will not.
