By my improved process now to be described I have done away with the necessity for any mechanical mixture of the ingredicuts and instead prepare lithopone ofany desired grade and in much purer form by a simple process or reaction, which at the same time produces some by-product of marked commercial value and one, preferably, that is easily soluble in water.

Second, the present invention provides a large-scale industrial production process with low production cost, high efficiency, energy saving, and stable product quality with an annual production capacity of several hundred thousand tons. Selective leaching of zinc by ammonia method, combined with ammonium persulfate iron removal, vulcanization method and zinc powder replacement method to remove heavy metal elements such as nickel, copper, lead, cadmium and arsenic, and metathesis reaction to obtain nZnS-B a S0 4 crystal filter cake. The nano-Lide powder product is obtained by directly drying and pulverizing without high-temperature calcination. The resulting product is of good quality and industrially operable.

In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.

One of the key advantages of using nano titania in coatings is its superior UV resistance. Nano titania can effectively absorb and scatter UV radiation, providing enhanced protection against UV-induced degradation of coatings. This property makes nano titania an ideal choice for exterior coatings exposed to sunlight, such as automotive coatings, building coatings, and marine coatings.
