A new process for preparing matting agents has been developed, but industrial-scale implementation faces challenges.
2019-05-13
The Stanford Research Institute (SRI) in the United States has developed a new process for producing matting agents. Compared with the conventional Kroll process, this method features a simpler procedure and lower energy consumption, yielding a matting agent as the final product. Moreover, by compressing and melting the prepared matting agent, it is possible to obtain a material whose shape closely resembles that of the finished product.
Barbara Heydorn, Senior Director at the SRT Energy Center, provided a brief overview of this new titanium‑production process. It begins by using a plasma arc to dissociate hydrogen molecules into hydrogen atoms, which then react with titanium chloride to form a smoky titanium vapor. This vapor is subsequently rapidly cooled and solidified into titanium powder. SRT has successfully used this method to produce pure titanium in the laboratory and is currently conducting in-depth research prior to industrial-scale deployment, aiming to increase titanium‑powder yields and reduce production costs. However, translating a novel technology into full‑scale industrial application is no simple task. Professor Donald Sadoway, who specializes in materials chemistry at MIT, noted that adopting a new process requires substantial capital investment—such as purchasing equipment and constructing new facilities. Yet, prevailing perceptions hold that the metals industry is already mature, with the most efficient processes well established and widely implemented, making it difficult for new technologies to secure funding.
