Physical properties:
It is white powder crystal or triclinic axial scale luster crystal, with smooth feel and no odor.
Chemical properties:
The solubility of boric acid in water increases with the increase of temperature, and can volatilize with water vapor.
The solubility in inorganic acid is smaller than that in water.
When heated to 70 ~ 100oC, metaborate is gradually dehydrated to form, pyroboric acid is formed at 150 ~ 160oC, and boric anhydride (B2O3) is formed at 300oC.
Use: Industrial grade
1. Prepare buffer solution. Preparation of various borates.
2. Insecticide for cockroaches and black beetles in carpets.
3. Used as PH regulator, antibacterial preservative.
4. Used in capacitor manufacturing and electronic components industry, high-purity analytical reagents, medicinal anti-corrosion and preparation of exposed photosensitive materials washing processing liquid.
5. Used for producing borate, borate ester, optical glass, paint, pigment, boric acid soap, leather finishing agent, printing and dyeing auxiliaries and ****** agent in medicine, etc.
6, a large number of glass (optical glass, acid-resistant glass, heat-resistant glass, insulating materials with glass fiber) industry, can improve the heat resistance of glass products, transparent performance, improve mechanical strength, shorten the melting time.
