3、Usage：

Glass and glass fiber
In the manufacture of insulating glass wool, textile fiberglass and borosilicate glass (heat-resistant glass, electric light source glass, glass burner, drugs, cosmetics bottles, hollow beads, optical lenses, sealed glass) and other areas, as provided by oxidation boron materials.

Ceramic and enamel glazes
Pentahydrate borax (Neobor) increase ceramics’ (such as tiles, tableware, ceramics and enamel device, etc.) compressive strength, abrasion resistance and chemical resistance. As the thermal expansion coefficient of B2O3 on the control of making the glaze to adapt the line to improve, but also can reduce the melting temperature of B2O3, prevent loss through. Makes the product more smooth and more perfect.
