WebBismuth is used to calibrate instruments employed in high-pressure studies because it has several well- characterized crystalline phases. Its phase diagram (below) shows the liquid phase and five solid phases that are stable above 1 katm (1000 atm) and up to 300° C. 100 v V Pressure (katm) 50 III IV II Liquid 0 300 100 200 WebHowever, lead-bismuth eutectic has a comparatively low melting temperature of 123.5 °C (254.3 °F), making melting a relatively easily accomplished task. Lead has a higher melting point of 327.5 °С, but is often used as a pool type reactor where the large bulk of lead does not easily freeze.
WebBismuth films with thicknesses between 6 and ∼30 nm were grown on Si (111) substrate by molecular beam epitaxy (MBE). Two main phases of bismuth — α-Bi and β-Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. β-Bi layers …
