Aluminum Industry Bauxite is one of the main raw materials for the production of aluminum. Through high-temperature smelting, bauxite can be converted into metallic aluminum, which is an important raw material for the manufacture of various aluminum alloys and aluminum products and is widely used in defense, aviation, electrical appliances, chemicals, and daily necessities.

Refractory materials: Refractory bauxite is widely used in the manufacture of วัสดุทนไฟ due to its stable properties at high temperatures. These materials are used as linings in high-temperature industrial furnaces such as hearths and furnaces in the production of steel, กระจก, เซรามิกส์, and chemicals.

Precision casting: Bauxite clinker can be processed into fine powder, which can be used to make molds in precision casting technology, and then used in precision casting of military industry, การบินและอวกาศ, communication instruments, machinery, and medical equipment.

Aluminum silicate refractory fiber: Bauxite is also the basic raw material for the production of aluminum silicate refractory fiber. This refractory fiber has the characteristics of lightweight, ทนต่ออุณหภูมิสูง, เสถียรภาพทางความร้อนที่ดี, การนำความร้อนต่ำ, and resistance to mechanical vibration. It has important applications in many industries such as steel, non-ferrous metallurgy, อิเล็กทรอนิกส์, ปิโตรเลียม, อุตสาหกรรมเคมี, การบินและอวกาศ, atomic energy, and national defense. It can also be used to make a substitute for refractory bricks, such as high-temperature kiln linings.

Other applications: Bauxite is also used to make alumina cement, grinding materials, เซรามิกส์, เป็นต้น. ในอุตสาหกรรมเคมี, bauxite can be used to produce various aluminum compounds for the production of chemical products.
