Because parts made from boron carbide have a higher rigidity and lower weight compared with those made from silicon carbide and alumina, boron carbide parts are important components for semiconductor manufacturing equipment and other components requiring high-temperature and abrasion resistance, including nozzles, mechanical seals and hard-disc substrates. However, making boron carbide parts with complex...

High-pressure die-cast (HPDC) aluminum alloys cannot normally be heated to high temperatures due to the presence of pores containing entrapped gases, which lead to the formation of surface blisters. CSIRO Materials Science and Engineering (Melbourne, Australia; edlinks.che.com/7371-548) has found that blistering can be avoided by using shorter solution-treatment times at lower temperatures. CSIRO says its...

Nanostructured microporous carbons containing well-dispersed metal nanoparticles have the potential to improve the performance of fuel cells or catalysis. However, traditional techniques for embedding metal particles in porous carbons (post-synthesis treatment either by impregnation, adsorption, or ion exchange) can lead to uncontrolled growth of metal particle size, shape and aggregation, which can cause...

A new process to produce titanium, called the TiRO process, has been developed by a team from CSIRO (Melbourne, Australia; edlinks.che.com/6901-538) through its Light Metals Flagship. The process is said to halve the cost of producing titanium metal components by: 1) Replacing the conventional Kroll-batch process with a more continuous process based on fluidized-bed (FB) technology; and 2) Using Ti’s...
