4N 99.99% Bismuth Ingot Siab Purity Bismuth Ingots
Product Description
Bismuth yog silvery dawb rau lub teeb daj lustrous hlau, tawv thiab nkig, yooj yim rau crush, nrog txias expansion thiab shrinkage yam ntxwv.Nyob rau hauv chav tsev kub, bismuth tsis hnov mob nrog oxygen lossis dej, ruaj khov hauv huab cua, thiab muaj hluav taws xob tsis zoo thiab thermal conductivity.Bismuth yog rhuab mus rau saum lub melting point thiab kub hnyiab, nrog lub teeb xiav nplaim, ua bismuth trioxide, thiab liab bismuth kuj yuav compounded sulfur thiab halogen.
