| Sodium tetraborate pentahydrate Usage And Synthesis |
| General Description | White odorless crystals or free-flowing powder. Density: 1.82 g cm-3. Soluble in water (38 g / L H2O at 20°C). Used in the manufacture of fiberglass insulation and sodium perborate bleach. |
| Reactivity Profile | Sodium tetraborate pentahydrate is non-combustible. Dissolves somewhat exothermically in water to give basic solutions. Of generally low chemical reactivity. When heated in a closed tube, starts to melt in its own water of crystallization at 128°C and becomes fluid at 140°C. When heated in the open, loses water of crystallization and then melts at 742°C. |

Application
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
borax 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.
Other applications:
Fertilizer, detergent, bleach detergent, flame retardant, antirust, binder, stabilizer, emulsifier etc.
Packing and Storage:
standard seaworthy packing
25kg bags/ 50kg bags,/1mt Jumbo bags
should be stored under cover in a cool, dry place; the bags should not be stacked more than 15 bags high.
