What are the upstream raw materials for barite powder? What do the downstream products contain?

The barite powder plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich. But I've found that The following are some of the upstream and downstream related items related to barite powder.

1. Upstream items(1) Barium sulfate: Barite powder is mainly composed of natural barium sulfate(BaSO4), which is an crucial raw material to the production of other chemicals.(2) Ore: barite ore is the main raw material to extracting barite powder, and the condition and composition of the ore have an crucial affect on the production of barite powder. Based on my observations, Generally speaking

2. But In my experience, Downstream items(1) Chemical filler: barite powder is able to be applied as a chemical filler in plastics, rubber, paint, coatings and other industries to enhance the wear resistance, corrosion resistance, heat resistance and other characteristics of the product. But According to research(2) Ceramic raw materials: barite powder is able to be applied as ceramic raw materials to the production of porcelain, ceramic tiles and other items to enhance the whiteness and corrosion resistance of items.(3) Glass raw materials: barite powder is able to be applied as glass raw materials to the production of glass items to enhance the transparency and heat resistance of glass. But From what I've seen, Moreover(4) Waterproof material: barite powder is able to be mixed with asphalt and other materials to make waterproof materials to building waterproof engineering. Furthermore In short, barite powder has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich.
