Crystalline silicon isimbi grey, amorphous silicon itema. Kwete-chepfu, isina kunaka. D2.33; Melting point 1410 ℃; Avhareji yekupisa simba (16 ~ 100 ℃) 0.1774cal /(g -℃). Crystalline silicon is atomic crystal, yakaoma uye inopenya, uye yakafanana nesemiconductors. Pakupisa kwekamuri, kuwedzera kune hydrogen fluoride, zvakaoma kuita nezvimwe zvinhu, zvisinganyunguriki mumvura, nitric acid uye hydrochloric acid, inonyungudika mu hydrofluoric acid uye lye. Inogona kusanganiswa neokisijeni uye zvimwe zvinhu pakupisa kwakanyanya. Iyo ine hunhu hwekuoma kwepamusoro, haina kunyura kwemvura, kupisa kupisa, acid resistance, kupfeka kusamira uye kuramba kuchembera. Silicon inoparadzirwa zvakanyanya muzvisikwa uye ine inenge 27.6% muEarth's crust. Kunyanya muchimiro chesilica uye silicates.
Silicon simbi pachayo haina chepfu kumuviri wemunhu, asi mukugadzirisa inoburitsa yakanaka silicon guruva, ine inosimudzira mhedzisiro pakufema turakiti. Pfeka midziyo yekudzivirira yakakodzera semasiki, magurovhosi, uye kudzivirira maziso paunenge uchibata simbi yesilicon.
Oral LDso yemakonzo: 3160mg/kg. High concentration inhalation inokonzera kushatirwa kwakapfava kwekufema turakiti uye zvinogumbura kana ichipinda muziso semutorwa muviri. Silicon powder inopindirana nechisimba ne calcium, cesium carbide, chlorine, diamond fluoride, fluorine, iodine trifluoride, manganese trifluoride, rubidium carbide, silver fluoride, potassium sodium alloy. Guruva rine njodzi zviri pakati nepakati kana rakaiswa mumurazvo wemoto kana kubatwa neoxidants. Chengetedza muimba yekuchengetera inotonhorera, yakaoma uye ine mhepo yakanaka. Ramba kure nemoto nekupisa. Iyo pasuru inofanira kuvharwa uye kwete kusangana nemhepo. Inofanirwa kuchengetwa zvakasiyana kubva kune oxidizer, uye usasanganise.
Pamusoro pezvo, simbi yesilicon ichaita neokisijeni mumhepo kuti ibudise gasi rinopfuta, uye kutarisisa kunofanirwa kubhadharwa kudzivirira kusangana nezvinopisa moto kana oxidants panguva yekuchengetedza nekufambisa.
