With the development of technology, the domestic and international cryolite market is still hot, and the country attaches great importance to environmental protection. Overall, international environmental issues pose a risk of rising costs for the electrolytic aluminum industry. With the development of technology, the domestic and international cryolite market remains hot. In recent years, the rapid expansion of China's electrolytic aluminum industry has further stimulated the development of the cryolite industry.

one α- Aluminum oxide, also known as nano aluminum oxide, exhibits a white fluffy powder state with a crystal form of xz-L14 α Type. The particle size is 20nm; Specific surface area ≥ 50m/g. Uniform particle size distribution, high purity and high dispersion. It has low specific surface area and high temperature resistant inertia, but it does not belong to Activated alumina and has almost no catalytic activity.

Except for metallurgical grade aluminum oxide, various types of aluminum oxide, aluminum hydroxide, and aluminum containing compounds are referred to as chemical aluminum oxide, which is collectively referred to as non metallurgical grade aluminum oxide internationally. Among them, those that undergo special processing and have certain differences in performance compared to metallurgical grade aluminum oxide are referred to as special aluminum oxide.

The production process of calcined alumina micropowder uses industrial aluminum hydroxide or industrial alumina as raw materials, and is calcined at appropriate temperature to form a stable crystal form α- Type alumina products; To calcine α- Alumina micropowder made from type A alumina through ball milling. High temperature calcined alumina powder products have a high melting point, excellent mechanical strength, hardness, high resistivity, and thermal conductivity. It can be widely used in industries such as electronic equipment, structural ceramics, refractory materials, wear-resistant materials, polishing materials, etc.

Alumina is a widely used inorganic compound, and its molecular formula is Al2O3. It has many excellent physical and chemical properties, making it widely used in industries, healthcare, electronics, construction, and other fields.

The titanium gold plating process on aluminum profiles belongs to the coating technology. It adds pre plating and electroplating process steps to the conventional titanium plating process. The aluminum profile process involves chemically treating the activated plated parts in an aqueous solution of salt and hydrochloric acid; The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium dodecyl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good results. The film hardness of the titanium aluminum profile produced by this process is HV ≈ 1500, and under the same conditions, it is 150 times more wear-resistant than 22 K gold plating. It can be processed into various forms of gold, color, black, and other bright series of aluminum profile products.
