Research on Reducing Compactness of Titanium Sponge

The optimal experiments for reducing compactness of titanium sponge were carried out,and the influences of feeding speed,reaction temperature,liquid height and feeding way on the compactness of titanium sponge were studied. The results show that the average barrel rate of titanium sponge can reach to 63.0% and 62.6% by multi-point feeding and reducing the feeding speed,respectively. By reducing the reduction temperature and liquid height by 100 ℃ and 150 mm,the average barrel rate of titanium sponge can reach to 61.3% and 61.2%,respectively. The obtained titanium sponge in the experiments meets the 0 grade of the national standard. It can be seen from SEM images that the products in the experiments have the original layered sponge structure.
