is a kind of titanium metal raw material that looks like burned slag, and is mainly used for the smelting of non-ferrous metal titanium. The produced titanium ingots can be used to process titanium plates, tubes, rods, etc. The following will focus on the properties and storage of sponge titanium. I believe everyone knows that titanium is a corrosion-resistant metal, but it is definitely not non-oxidizing, because non-corrosive substances do not exist, so titanium is not non-oxidizing, especially at high temperatures, it is very easy and Oxygen is bound, but its oxide is extremely dense, which can prevent further corrosion by oxygen. Sponge titanium is a loose porous sponge with a large surface area and is relatively active. As we all know, the larger the surface area, the larger the contact surface with air, the higher the activity, and it is very easy to react with gas and water, and it is also very active. Easily oxidized. Oxygen is an impurity element in titanium, so if the oxygen content exceeds the standard, sponge titanium cannot be used and can only be scrapped.
According to the available data, there is no experience of long-term storage of titanium sponge. According to the properties of sponge titanium and the experience of various titanium processing plants, sponge titanium must be used at any time, and the storage should not exceed one year. In the 1970s, because people did not know much about the properties of sponge titanium, they once received a batch of sponge titanium. At that time, it was a barrel of 100 kilograms, and the particle size was larger than that of today. And this batch of titanium sponge was received less than half a year ago, some experts pointed out that the titanium sponge is not suitable for long-term storage, so the bureau quickly released the titanium sponge from the warehouse and processed it into titanium ingots from the factory for storage. The storage before and after is less than one year. Therefore, in the current situation, long-term storage of titanium sponge is inexperienced.
