Technical FAQs 4

How does sulfur affect glass matrices?

Under reducing conditions, sulfur can incorporate into glass matrices, significantly influencing the polymerization of the glass network and altering their structures, properties and functionality.

Does sulfur increase glass stability?

Thermal analysis of the tested glasses supported the structural studies and demonstrated that the addition of sulfur initially reduces materials’ glass stability, leading to its increase after SO3 content reaches 1 mol.%.

Why is sulfur a low soluble element in glass?

Partitioning of sulfur in the molten salt phase (once its solubility limit is exceeded) has also been suggested as a mechanism for its low retention in the glass—volatilization of this element can occur from the salt layer even more readily than from the glass.

How much iron is in solar glass?

As one of the most crucial components of solar installations, photovoltaic glass demands high transparency. Therefore, strict requirements are imposed on the iron content in the silicon raw materials used for producing solar glass, with Fe2O3 content typically ranging from 140 to 150 ppm.
