polysilicon ine grey metallic luster uye density ye2.32 ~ 2.34g/cm3. Melting point 1410℃. Boiling point 2355℃. Soluble mumusanganiswa wehydrofluoric acid uye nitric acid, isinganyunguriki mumvura, nitric acid uye hydrochloric acid. Kuoma kwayo kuri pakati peiyo yegermanium nequartz. Inoputsika pakupisa kwekamuri uye inotsemuka nyore nyore kana ichichekwa. Inova ductile kana ichipisa kusvika pamusoro pe800℃, uye inoratidza pachena deformation pa1300℃. Iyo haishande pakudziya kwekamuri uye inopindirana neokisijeni, nitrogen, sarufa, nezvimwewo pakupisa kwakanyanya. Mune yakanyanya-tembiricha yakanyungudutswa, ine yakakura kemikari kuita uye inogona kuita nechero chero chinhu. Iyo ine semiconductor zvimiro uye yakakosha zvakanyanya uye yakanakisa semiconductor zvinhu, asi kuteedzera huwandu hwehutsvina hunogona kukanganisa zvakanyanya kuita kwayo. Inoshandiswa zvakanyanya muindasitiri yemagetsi sechinhu chakakosha pakugadzira semiconductor radio, tepi rekodha, mafiriji, mavara maTV, vhidhiyo rekodha, uye emagetsi makomputa. Inowanikwa nekloriniya yakaoma silicon poda uye yakaoma hydrogen chloride gasi pasi pemamwe mamiriro, uyezve condensing, distilling, uye kuderedza.
polysilicon inogona kushandiswa seyakagadzirwa zvinhu zvekudhonza imwechete crystal silicon. Musiyano uripo pakati pepolysilicon uye single crystal silicon inonyanya kuratidzwa mune zvemuviri zvivakwa. Semuenzaniso, iyo anisotropy ye mechanical properties, optical properties uye thermal properties haisi pachena zvishoma pane iyo imwe crystal silicon; maererano nemagetsi emagetsi, iyo conductivity yepolysilicon crystals zvakare yakanyanya kuderera kupfuura iyo yeimwe crystal silicon, uye kunyange ine inenge isina conductivity. Panyaya yekushanda kwemakemikari, musiyano pakati pezviviri zvishoma. polysilicon uye imwechete crystal silicon inogona kusiyaniswa kubva kune imwe neimwe muchitarisiko, asi iyo chaiyo yekuzivikanwa inofanirwa kutariswa nekuongorora iyo crystal plane kutungamira, conductivity mhando uye resistivity yekristaro. polysilicon ndiyo yakananga mbishi yekugadzira imwe chete crystal silicon, uye ndiyo yakakosha ruzivo rwemagetsi zvemazuva ano semiconductor zvishandiso zvakaita sehungwaru hwekugadzira, kudzora otomatiki, kugadzirisa ruzivo, uye kutendeuka kwephotoelectric.
