· JVASP-68111· SrTa2Be

SrTa2Be is an experimental ceramic compound combining strontium, tantalum, and beryllium into a dense, rigid material. This research-phase compound belongs to the family of complex oxide and intermetallic ceramics being investigated for high-performance structural and electronic applications where extreme stiffness and thermal stability are required. As a beryllium-containing ceramic, it represents emerging work in ultra-high-modulus materials, though industrial adoption remains limited due to beryllium's toxicity concerns and the material's relative novelty.
