These specific properties arise from the structural role played by boron in the glass. Boron is a network former and is fully integrated to the glass structure in the form of different structural units, in which its coordination can be either three-fold and/or four-fold (boron speciation).
Incorporating boron oxide into another glass enables numerous desired features, such as the regulated reduction of the operating temperature of the glass . The BG system is ideal for scientific research because it reacts effectively to multiple property and structure investigations.
Those qualities also increase the manufacturability of new glasses by ensuring the glass flows smoothly through Corning's systems. As a result, boron has made numerous technical glasses possible, including our new Corning® Astra™ Glass, a glass substrate that enables extremely high pixel density for high-performance displays.
Boron is a network former and is fully integrated to the glass structure in the form of different structural units, in which its coordination can be either three-fold and/or four-fold (boron speciation). The way boron is incorporated to the glassy network depends on the composition and melting conditions of the glass.
The arrangement of this network will in turn govern the extent of B degassing from the melt. Boron oxide is an ingredient in many commercial glasses [2,3]. Incorporating boron oxide into another glass enables numerous desired features, such as the regulated reduction of the operating temperature of the glass .
