Ba7SrAl16Si30
metal· Ba7SrAl16Si30
Ba₇SrAl₁₆Si₃₀ is an intermetallic compound belonging to the aluminosilicate family, combining alkaline earth elements (barium and strontium) with aluminum and silicon in a complex crystal structure. This material is primarily studied in research contexts as a candidate for thermal barrier coatings and high-temperature structural applications where low thermal conductivity is advantageous. Its combination of lightweight constituent elements and ceramic-like thermal properties makes it of interest for aerospace and automotive industries seeking alternative materials to conventional metal alloys or traditional oxide ceramics.
