  • Chemical Properties and Structure Borax (Sodium Tetraborate Pentahydrate, Na2B4O7.5H2O) is a sodium borate compound containing 5 mol of water. It belongs to the monoclinic crystal system with the space group C2/c. In its crystallographic structure, each sodium ion is positioned in an inversion symmetry and exhibits a distorted octahedral geometry. Borax readily dissolves in water, forming conjugated acid-base pairs NaB(OH)4 and H3BO3.
  • Industrial and Agricultural Uses Widely used in industry, borax is included in glass production to enhance viscosity, surface hardness, and durability, contributing to heat insulation.
    Applied in agriculture to increase productivity and improve product quality by acting as a micronutrient for plant growth, promoting root growth, and influencing photosynthesis and fertilization.
  • Chemical Cross-linking Agent Borax acts as a chemical cross-linker due to its low toxicity, cost-effectiveness, and water solubility.
    In an aqueous solution, borax dissociates into trigonal boric acid (B(OH)3) and tetrahydroxy borate ion (B(OH)4鈥?), capable of reacting with functional groups of polymers.
    The pH of the system influences cross-linking, with higher pH resulting in increased cross-linking reactions and enhanced mechanical properties of polymer films.
  • Applications in Hydrogel Formation Utilized in the preparation of environmentally friendly hydrogels from cellulose, borax facilitates cross-linking between hydroxyl groups of cellulose chains.
    The incorporation of borax enhances the swelling ratio and gel fraction of cellulose hydrogels, providing super absorbent features.
    Cross-linked cellulose-based hydrogels demonstrate antibacterial activity against gram-positive bacteria and flame-retardant properties.
  • Safety and Eco-Friendliness Borax is considered non-toxic and eco-friendly, making it suitable for various applications in industry, agriculture, and hydrogel formation. It is an efficient cross-linking agent, enabling the rapid formation of hydrogels in substances with active hydroxyl groups.
