How to Mix Calcium Chloride for Dust Control | Hunker
According to the United States Department of Agriculture Forest Service, calcium chloride is an effective means of reducing dust and fine debris from being distributed by traffic on roads. Because it''s a common salt, it is a fairly environmentally friendly solution to dust problems.
Added network modifiers, such as sodium, potassium, or boron oxide, lower the melting point and lower the chemical durability, whereas added network stabilizers, such as calcium and aluminum oxides, improve the durability of the glass. Colored glass (e.g., aer glass) is produced by transition metal oxides such as iron oxides.
