Firstly, let's delve into how titanium metal was extracted from nature and introduced into human society. Due to its extremely high chemical activity, titanium metal mainly exists in the form of titanium dioxide and titanate in nature, and often coexists with elements such as iron, calcium, magnesium, silicon, aluminum, manganese, and rare earths. In order to extract pure titanium from these complex minerals, we need to go through a series of intricate technological processes.
The magnesium reduction-vacuum distillation method dominates the process of producing titanium sponge.This method first requires the enrichment of titanium minerals, and then converts them into titanium tetrachloride through a chlorination process.Next, magnesium is used to reduce the titanium tetrachloride under the protection of argon gas to produce titanium sponge. Magnesium and magnesium chloride can be further separated and removed by vacuum distillation, resulting in a pure titanium sponge product.
Titanium sponge, as the basic material for all finished titanium products and titanium powder, its quality is crucial to the performance of titanium products. In China, titanium sponge is divided into 7 grades according to chemical composition and Brinell hardness, ranging from grade 0A to grade 5. Among them, Grade 0A and Grade 0 titanium sponge have the highest purity and are mainly used in high-end industrial and military fields. These fields have extremely high performance requirements for materials, especially in the aerospace industry, where precision parts must use high-quality sponge titanium to ensure their safety and reliability.In the medical field, high-quality titanium sponge also plays an important role in the production of implants and surgical devices, which require high standards of biocompatibility and corrosion resistance.
Grade 1 titanium sponge is widely used in fields such as aerospace, medical, and sports and leisure. In the aerospace field, it is used to manufacture key components such as engine parts and fuselage structures for aircraft and rockets. In the medical field, grade 1 titanium sponge is used to manufacture medical materials and equipment such as artificial joints and surgical instruments. In the sports and leisure industry, it is used to manufacture high-performance sports equipments and Outdoor Gears.
For fields with low purity requirements, such as chemical engineering, salt production, and metallurgy, grade 2 and grade 3 titanium sponge are mainly used.Although these titanium sponge have slightly lower purity, their prices are more affordable and can meet the basic demand for Titanium Materials in these fields. The price of grade 4 titanium sponge is more affordable and suitable for large-scale application in the chemical industry.
Although the purity of grade 5 titanium sponge is only 98.5%, it does not mean that it has no application value.In some fields that do not require high purity, such as the construction field, grade 5 titanium sponge has become a good choice for cost reduction and efficiency increase by virtue of its relatively low price and sufficient performance.Through the reasonable application of grade 5 titanium sponge, construction costs can be effectively reduced without affecting the quality of construction.
In summary, titanium sponge plays a crucial role in the titanium metal industry. From high-end industrial fields to daily life applications, different grades of titanium sponge are playing their unique roles and values.
