- The history of lithopone factories in China dates back to the early 20th century when the first production facilities were established. The industry grew rapidly in the following decades, driven by the country's rapid industrialization and demand for raw materials. Today, China is the world's largest producer and exporter of lithopone, accounting for over 50% of global production.
- TiO2 technology manufacturers play a significant role in the development and innovation of TiO2 products. These manufacturers are constantly researching and implementing new technologies to improve the efficiency and sustainability of TiO2 production. By investing in research and development, TiO2 technology manufacturers are able to stay ahead in the market and meet the growing demand for high-quality TiO2 products.
- 5公斤氟钠钠。 In the leaching step, each cubic meter of ammonia - ammonium sulfate solution was added 0. 3~0. 5kg sodium fluorosilicate. The purpose is to make the ammonia leaching reaction easier and more thorough. Adding an appropriate amount of sodium fluorosilicate can break the package of zinc-containing particles by a kind of ultrafine particles such as calcium hydroxide formed during the dissolution and conversion process of calcium sulfate in the ammonia solution. , the ultra-fine particles are layered and peeled off to achieve leaching.

To overcome this challenge, manufacturers use advanced technology and processes to monitor and control the buff percentage of their products. This may involve the use of sophisticated equipment to measure the coating thickness of titanium dioxide particles, as well as automated systems to adjust the level of coating as needed. By carefully controlling the buff percentage, manufacturers can ensure that their products meet the specifications of their customers and maintain a high level of quality and performance.
Titanium dioxide is a food additive that can be found in over 3,000 different products in EWG’s Food Scores database.
VB Chemicals large range of engineered Lithopone “Seal family” fully meets the European regulatory standards and is suitable for every application such as:
Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.
In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2. With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
