In the field of raw materials for chemical production, kaolin, as an important non-metallic mineral resource, is widely used in various industrial fields. There are many upstream and downstream related products of white clay, and some of the main upstream and downstream products will be described in detail below.

upstream products:

1. Quartz sand: Quartz sand is one of the main raw materials of kaolin, used to prepare high-purity kaolin. The quality and purity of quartz sand have an important influence on the production of white clay.
2. Feldspar: Feldspar is another common kaolin raw material. After high-temperature calcination with quartz sand, high-quality kaolin can be prepared.

downstream products:

1. Ceramic products: As an important raw material for the ceramic industry, kaolin can be used to produce various ceramic products, such as daily-use ceramics, building ceramics, and electric ceramics. The kaolinite component in kaolin clay helps to improve the strength and toughness of ceramics.
2. Refractory materials: kaolin has good fire resistance and can be used to produce various refractory materials, such as refractory bricks and refractory mud. These refractory materials are widely used in iron and steel, non-ferrous metal smelting and other fields.
3. chemical packing: kaolin can be used as chemical packing in various chemical reactors and absorption towers and other equipment to improve the mass transfer and heat transfer efficiency of the equipment.
4. Papermaking filler: kaolin can be used as papermaking filler to improve the gloss and opacity of paper, while reducing production costs.

In short, kaolin has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are numerous, which is of great significance for promoting industrial development and improving product quality.
