Što je Stannic Oksid

Our TOPLUS has many years of experience.Our TOPLUS knows a lot about Stannic oxide.SnO2 is also an excellent transparent conductive material. It is the first transparent conductive material to be put into commercial use. In order to improve its conductivity and stability, it is often used for doping, such as SnO2:Sb, SnO2:F, etc. Both SnO2 and its doping have a tetragonal rutile structure as shown. Red is O, black is Sn, and SnO2 is composed of two Sn and four O atoms, and the lattice constant is a=b=0.4737 nm, c=0.3186 nm, and c/a=0.637. O^2-=0.140 nm, Sn^4+=0.071 nm. SnO2 is an n-type wide bandgap semiconductor with a forbidden band width of 3.5-4.0eV, visible light and infrared transmittance of 80%, a plasma edge of 3.2μm, a refractive index of >2, i koeficijent izumiranja 0.sno2 ima snažnu adheziju. Ima silu veza do 20 MPa sa staklom i keramikom, tvrdoćom od 7-8 i dobru kemijsku stabilnost. Može izdržati kemijsko jetkanje. SNO2 djeluje kao vodljivi film, a njegovi nosači uglavnom potječu od kristalnih oštećenja, odnosno o slobodnim radnim mjestima i elektronima koji se isporučuju doping nečistoćama.
