The projects include a purified phosphoric acid (PPA) project with an annual output of 400,000 metric tons, two anhydrous hydrogen fluoride projects with an annual output of 30,000 tons each, a gypsum powder project for building materials with an annual output of 1.2 million tons, a 30-million square meter paperless gypsum board project and a major building materials and industrial equipment project.
The group also said one of the two anhydrous hydrogen fluoride projects is expected to be finished by the end of April.
The group plans to build itself into one of the world's biggest and most competitive fluoride-related resource suppliers by expanding its global annual production capacity of anhydrous hydrogen fluoride to 500,000 tons in the short future.
By taking Guizhou as an important base, China is able to build a green industrial chain system with low carbon emissions－from upstream phosphate mining, phosphorus and fluorine chemical production to downstream applications, said He Guangliang, also president of State-owned Guizhou Phosphate Chemical Group, the world's largest purified wet phosphoric acid and anhydrous hydrogen fluoride provider based in the Southwest China province.
In terms of function, the white paper found that demand for fresh breath, scientific fluoride, personalized flavors, soft touch like velvet, as well as convenience, health and exquisite care has been upgraded.
He said several groups are developing thorium-breeding molten salt reactors, otherwise known as liquid fluoride thorium reactors.
