Boric acid

Boric acid, chemical formula H₃BO₃, is a white powdery crystal or a scaly glossy crystal on a tri-oblique axis, with a smooth feel and no odor. Soluble in water, alcohol, glycerin, ethers and essential oils, the aqueous solution is weakly acidic. Silicon-manganese alloy particles are widely used in the glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber for insulating materials) industry, which can improve the heat resistance and transparency of glass products, improve mechanical strength, and shorten melting time.
