| Boric Acid Molecular formula:H3BO3 B:17% Water insolubles:0.005% SO4:0.003% CAS: HS code:28100020 Boric acid is actually boron oxide hydrate (B2O3·3H2O), white powder crystal or triclinic axial surface scale luster crystal, and skin contact with greasy feel, no smell. Soluble in water, alcohol, glycerin, ether and essential oil, no smell, taste slightly sour bitter with sweet. Dew, left unchanged in the air, can evaporate with steam. When heated to 100-105 ºC metaborate lose a molecule of water and formation; In 104-160 ºC heating duration time into focal boric acid, higher temperature of water is formed. Boric acid can be dissolved in 18ml cold water, 4ml boiling water, 18ml cold ethanol, 6ml boiling ethanol and 4ml glycerol at a PH of 5.1.1g in 0.1mol/L aqueous solution. The solubility in water increases with the addition of citric acid and tartaric acid. Relative density: 1.4347, melting point 184 ºC (decomposition), the boiling point of 300 ºC. |

| Product use | |
| 1. Prepare various borates, insecticides for cockroaches and black beetles in carpets. 2. Used medically as hemostatic and preservative, pH value regulator, disinfectant, antibacterial preservative, etc. 3. Used for preparing borate, borate ester, optical glass, paint, pigment, boric acid soap, leather finishing agent, printing and dyeing assistant and disinfectant on medicine. 4. Used in capacitor manufacturing and electronic component industry, high purity analytical reagent, pharmaceutical disinfection and corrosion prevention, and preparation of exposed photosensitive materials for washing and processing pharmaceutical industry. 5. Used in glass, enamel, ceramics, medicine, metallurgy, leather, dye, pesticide, fertilizer, textile and other industries. 6. Used as chromatographic reagent and buffer preparation. 7, a large number of glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber insulation materials) industry, can improve the heat resistance of glass products, transparent performance, improve mechanical strength, shorten melting time. 8, in the enamel, ceramic industry, used to enhance the gloss and fastness of enamel products, is also one of the ingredients of glaze and pigment. 9, metallurgical industry as an additive, cosolvent, especially boron steel with high hardness and good rolling ductility, can replace nickel copper. 10, boric acid has corrosion resistance, can be used as a preservative, such as: wood corrosion. 11, in metal welding, leather, photography and other industries and dyes, heat-resistant and fireproof fabrics, artificial gems, capacitors, cosmetics manufacturing are used in it. 12, in agriculture can be used as boron fertilizer, because boric acid contains 17% of the trace element boron. It has a fertility effect on many crops and can improve crop quality and yield. 13. Boric acid can be used as industrial batting material. |

| Should be stored in a dry and clean warehouse, not piled up in the open air, should avoid rain or damp. They should be carried in caravans, cabins or covered cars and should not be stacked with damp goods and coloured materials. The means of transport must be dry and clean. |
| The application method and suggestion of boric acid as boric fertilizer | |
| The application method and suggestion of boric acid as boric fertilizer Application of boron fertilizer is a scientific, technical very strong job, before the use of boron fertilizer according to soil conditions, different crops need amount of boron, different reproductive stage, the amounts of boron are required, the crop sensitivity of boron, climate condition, the balance of the relationship between nutrient elements, and the symptoms of boron deficiency in crops such as through scientific computing to fertilization, to ensure that the proper application of boron fertilizer, avoid boron, in addition to the above factors, the application of boron fertilizer should be based on a variety of boron fertilizer condition to select the correct application method, will now be part of the boron fertilizer application method introduction is as follows: The pure boric acid contains B2O3:56.3%, and B: 17.48%. Industrial grade I products contain B2O3:55.7%, while B: 17.29%. Boric acid is soluble in water, the aqueous solution is weak acid, its application range and method are the same as borax, the difference is boric acid contains boron content is about 54% higher than borax, in the dosage or dilution concentration should be reduced accordingly, so as not to waste or cause boron harm. |
