What is Titanium Sponge?

Sponge metal titanium produced by metal thermal reduction method. Purity% (mass) is generally 99.1-99.7. The total impurity element% (mass) is 0.3 to 0.9, the impurity element oxygen (mass) is 0.06 to 0.20, and the hardness (HB) is 100 to 157. It is divided into five grades of WHTiO to MHTi4 according to the difference in purity. It is the main raw material for preparing industrial titanium alloy. The production of sponge titanium is the basic link of the titanium industry. It is the raw material of titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, put it into a sealed stainless steel tank, fill it with argon, and make them react with magnesium metal to obtain "sponge titanium". Such porous "sponge titanium" cannot be used directly, and they must be melted into a liquid in an electric furnace to be cast into titanium ingots.

Large-scale titanium metallurgical companies are all magnesium-titanium complexes, and most manufacturers use the integrated reduction-distillation process. This process is called combined method or semi-combined method, which realizes the raw material Mg-Cl2MgCl2

During the high-speed development of China for more than 10 years, China's titanium industry has been seriously out of control. Many localities have developed titanium projects in the "violent" local protectionist rush to the beach, resulting in a serious oversupply of the titanium market. But it also cannot change the status quo of actual production capacity far exceeding demand. For example, in 2012, although the total amount of titanium materials was more than 60,000 tons, the export of titanium ingots increased significantly. The total titanium ingot inventory of many titanium processing companies such as Baosteel and Baotai accumulated to more than 5,000 tons. Also collected and stored 4,000 tons of titanium ingots. It can be seen that the domestic titanium material output has increased significantly and the demand has not increased simultaneously. On the contrary, it can be seen that the development of the foreign titanium industry is more rational, unlike the domestic development, which is "glorious" in the runaway.

In 2012, the economy began to recover, and China's titanium industry market was still sluggish, but we must not blame it for the financial crisis and the European debt crisis. We must find the cause in our out of control development. Otherwise, various economic crises After the end, the development crisis of desperate projects in China's titanium industry still exists. Looking at the development path of the titanium industry in China for more than 10 years, we have seen such a cycle with pain: the first expansion of production the first reshuffle the second expansion of production the second reshuffle ... China's titanium industry From the 1960s to 2004, the production capacity of both titanium and titanium materials was very small. For example, China produced 2,000 tons of sponge titanium at the end of 2000. However, with the gradual increase in titanium demand at the end of 2004, by 2005 The price of titanium has risen from 50,000 to 60,000 yuan per ton to 200,000 to 300,000 yuan per ton, and there has been a phenomenon of profiteering with no market price. The first large-scale expansion in the titanium sector has quietly occurred, and the production capacity in just a few years It quickly turned over 60 times. Expansion, adjustment, pain, after the reshuffle in 2012, China's actual output of sponge titanium increased by more than 40 times in 2000. ^[1]
