Fields of application
- Industrial sector
📌 Glass and Ceramics
Function: Serves as a boron source in the production of borosilicate glass (e.g., heat-resistant cookware, laboratory vessels, mobile phone cover plates), significantly enhancing thermal stability, impact resistance, and chemical durability. Recommended applications: OLED display cover plates, high-end ceramic glazes.
📌 Optimal boron solution
Function: Environmentally friendly, halogen-free flame retardant; forms a vitrified carbon layer upon combustion, providing thermal insulation and oxygen exclusion.
Suitable materials: timber, textiles, plastics, cable sheathing.
Advantages: Low toxicity, smoke suppression, synergistic enhancement with other flame retardants.
📌 Metallurgical industry
Function: Acts as a flux to remove oxides from metal surfaces during welding/smelting processes, enhancing joint strength and metal purity.
📌 Nuclear Industry
Function: Utilising the strong neutron absorption capacity of boron-10 isotopes, it serves as a neutron absorber and moderator in nuclear power plants, ensuring operational safety.
Requirements: High purity and low impurity levels are essential. Youboron can supply products meeting nuclear-grade standards. - Agricultural sector
📌 Trace element fertiliser
Function: Supplies plants with essential boron, preventing issues such as poor fruit set, fruit drop, and stunted growth in crops including oilseed rape, cotton, and fruit trees.
Application method: Foliar spray or soil application, also suitable as a raw material for compound fertilisers.
Advantages: Excellent water solubility, rapid absorption, increased yield and improved quality. - Pharmaceuticals and Personal Care
📌 Disinfection and Preservation
Usage: Diluted solution for use as an eye wash, in the care of skin infections, and as an adjunct treatment for eczema, exhibiting mild antibacterial and antifungal properties.
Dosage forms: boric acid ointment, eye drops, mouthwash, etc.
📌 cosmetics
Purpose: As a pH adjuster and preservative in products such as emulsions and face masks. - Other fields
Chemical raw material: Used in the synthesis of borax, borate esters, boron carbide (a superhard material), and other compounds.
Electroplating: Serves as a buffer and brightener in nickel plating electrolytes, enhancing coating quality.
Wood preservation: Formulated with borax for insect and mould prevention in timber.
Packaging and Logistics
