Silicon hlau
Silicon hlau feem ntau hu ua metallurgical qib silicon lossis nws yog xim hlau silicon vim nws ci xim hlau xim. Nyob rau hauv kev lag luam nws yog tsuas yog siv raws li ib tug alumnium alloy los yog ib tug semiconductor khoom. Silicon hlau kuj tseem siv hauv kev lag luam tshuaj los tsim cov siloxanes thiab silicones. Nws raug suav hais tias yog ib qho khoom siv raw khoom hauv ntau thaj tsam ntawm lub ntiaj teb. Kev lag luam thiab daim ntawv thov tseem ceeb ntawm silicon hlau nyob rau hauv lub ntiaj teb no tseem loj hlob. Ib feem ntawm kev lag luam thov rau cov khoom siv raw no tau ntsib los ntawm tus tsim khoom thiab xa tawm ntawm silicon hlau - UrbanMines.
