Enwere ike iji eriri sapphire otu kristal Al₂O₃ ebe mgbaze nke nnyefe anya dị elu 2072℃ maka ihe windo laser

Nkọwa Dị Mkpirikpi:

E ji otu kristal alumina (Al₂O₃) mee eriri sapphire, nke bụ ihe nwere ike igwe dị elu, iguzogide kemịkalụ na ezigbo ike okpomọkụ. Sapphire bụ nke usoro kristal hexagonal, oke nnyefe ọkụ bụ 0.146.0μm, ma nwee ike izipu ihe anya dị elu na eriri 3.05.0μm. Ebe agbaze nke sapphire dị elu ruo 2072 ° C, ike ya dịkwa naanị na dayamọnd, yabụ eriri sapphire nwere oke ike iguzogide okpomọkụ na ike igwe.
