polysilicon ali ndi imvi zitsulo zonyezimira ndi kachulukidwe wa 2.32 ~ 2.34g/cm3. Mtengo wa 1410℃. Malo otentha 2355℃. Kusungunuka mu chisakanizo cha hydrofluoric acid ndi nitric acid, osasungunuka m'madzi, nitric acid ndi hydrochloric acid. Kuuma kwake kuli pakati pa germanium ndi quartz. Imaphwanyika kutentha ndipo imasweka mosavuta ikadulidwa. Imakhala ductile ikatenthedwa kufika pamwamba pa 800℃, ndikuwonetsa kusinthika kowonekera pa 1300℃. Sichigwira ntchito kutentha kwa chipinda ndipo imakhudzidwa ndi mpweya, nayitrogeni, sulfure, ndi zina zotero pa kutentha kwakukulu. Pamalo osungunuka kwambiri, imakhala ndi zinthu zambiri zamakina ndipo imatha kuchitapo kanthu ndi pafupifupi chilichonse. Ili ndi mawonekedwe a semiconductor ndipo ndi chinthu chofunikira kwambiri komanso chapamwamba kwambiri cha semiconductor, koma zonyansa zochulukira zimatha kukhudza kwambiri mayendedwe ake. Amagwiritsidwa ntchito kwambiri m'makampani amagetsi ngati chinthu chofunikira popanga ma wayilesi a semiconductor, zojambulira matepi, mafiriji, ma TV amtundu, zojambulira makanema, ndi makompyuta apakompyuta. Amapezedwa ndi chlorinating youma silicon ufa ndi youma mpweya wa hydrogen chloride pansi pazifukwa zina, ndiyeno kufinya, kusungunula, ndi kuchepetsa.
polysilicon angagwiritsidwe ntchito ngati zopangira kukoka single crystal silikoni. Kusiyana pakati pa polysilicon ndi silikoni imodzi ya kristalo kumawonekera makamaka pazinthu zakuthupi. Mwachitsanzo, anisotropy of mechanical properties, optical properties and thermal properties ndizochepa kwambiri kuposa za crystal crystal silicon; kutengera mphamvu zamagetsi, madutsidwe a makristalo a polysilicon nawonso ndi ochepera kwambiri kuposa silicon imodzi ya crystal, ndipo ngakhale alibe madulidwe. Pankhani ya mankhwala, kusiyana pakati pa awiriwa ndi kochepa kwambiri. polysilicon ndi single crystal silicon zitha kusiyanitsa wina ndi mzake m'mawonekedwe, koma chizindikiritso chenicheni chiyenera kuzindikirika pofufuza momwe kristalo imayendera, mtundu wa conductivity ndi resistivity wa kristalo. polysilicon ndiye zida zachindunji zopangira silicon imodzi ya crystal, ndipo ndizomwe zimafunikira pazidziwitso zamagetsi pazida zamakono za semiconductor monga luntha lochita kupanga, kuwongolera zokha, kukonza zidziwitso, ndi kutembenuka kwamagetsi.
