Background
In the building field, it is required to apply to various plates, bricks and tiles, however, as resources are exploited and become scarce, it is increasingly difficult and costly to prepare plates, bricks and tiles from natural resources. In addition, with the development of a large amount of mineral products, a large amount of waste is also piled up like a mountain. The boric sludge is waste residue generated in the production of boric acid, borax and other products, is offwhite and yellowish white powdery solid, is alkaline, contains boron oxide, magnesium oxide and other components, and is commonly called as boric sludge. The stockpiling and disposal of the boric sludge not only occupies a large amount of land, but also can alkalize soil near a storage yard and cause migration and transformation of boron, thereby causing environmental pollution. A large amount of boron mud exists in the Dandong of Liaoning, and has important significance for benefiting the Dandong area if the boron mud can be reasonably utilized.
