Liaoning production base is located in Dashiqiao City, Liaoning Province, China. It has rich high-quality boron ore resources. In the early stage, it mainly used industrial boric acid to provide high-quality boric acid for the local steelmaking industry. Now it has gradually developed into a high-end boric acid production base of Del Boron Industry, with an annual output of more than 5000 tons of high-purity boric acid, which is mainly used in glass, ceramics, liquid crystal panel, medicine and other new material industries, while producing boron carbide, boron nitride, amorphous boron powder and boron compounds and other related products.
