Zvinhu zveTellurium dioxide, kunyanya nano-level yekuchena kwepamusoroTellurium Oxide, zvave zvichiwedzera kukwezva kutariswa kukuru muindasitiri. Saka ndeapi maitiro e nano Tellurium Oxide, uye ndeipi nzira chaiyo yekugadzirira? Chikwata cheR & D cheUrbanMines Tech Co., Ltd.yapfupisa chinyorwa chino kuti itaure nezveindasitiri.
Mumunda wesainzi yezvinhu zvemazuva ano, tellurium dioxide, sechinhu chakanaka kwazvo che acousto-optic, ine hunhu hwe high refractive index, large Raman scattering transition, good nonlinear optics, good electrical conductivity, acoustoelectric properties, high internal transmittance ye ultraviolet ne visible light, nezvimwewo. Tellurium dioxide inoshandiswa zvakanyanya muma optical amplifiers, acousto-optic deflectors, filters, optical conversion…
Zvinhu zveNanomaterials zvine hunhu hwenzvimbo yakakura uye saizi diki yezvikamu, izvo zvinogona kuita kuti zvibudise mhedzisiro yepamusoro, mhedzisiro yequantum uye mhedzisiro yehukuru. Saka, tsvakiridzo yakadzama pamusoro pezvinhu zveTellurium Dioxide Nanomaterials inokosha zvikuru.

Saka, tsvakiridzo yakadzama pa tellurium dioxide nanomaterials inokosha zvikuru. Parizvino, nzira dzekugadziriratellurium dioxideZvinhu zve nanomaterial zvinokamurwa kuva nzira yekupisa uye nzira ye sol. Nzira yekupisa ndiyo nzira yekubuda kwe evaporation zvakananga elemental tellurium solid powder pasi pemamiriro ekupisa kwakanyanya kuti pave ne oxide itsva. Zvakashata ndezvekuti reaction inoda tembiricha yakakwira, michina inodhura, uye utsi hune chepfu hunogadzirwa. Zvinhu zvakawanda zve tellurium dioxide nanomaterials zvakagadzirwa ne evaporation. Zvinhu zveTe elemental particles zvinobviswa nekushandisa air microwave plasma flame kugadzira spherical tellurium dioxide nanoparticles ine saizi ye particle distribution ye 100-25nm. Park et al. vakabvisa Te elemental powder muchubhu ye quartz isina kuvharwa pa500°C, vakagadzirisa Ag film pamusoro peSiO2 nanorods, vakagadzira Ag functionalized tellurium dioxide nanorods ine dhayamita ye 50-100nm, uye vakaishandisa kuona huwandu hwe ethanol gas. Nzira ye sol inoshandisa property ye tellurium precursors (kazhinji tellurite uye tellurium isopropoxide) kuti ive nyore kushandisa hydrolyzed. Sisitimu yesol inopenya yakagadzikana inoumbwa mushure mekuwedzera acid catalyst pasi pemamiriro emvura. Mushure mekusefa nekuomesa, tellurium dioxide nano-solid powder inowanikwa. Nzira yacho iri nyore kushandisa, haikuvadzi nharaunda, uye reaction haidi tembiricha yakakwira. Shandisa hunhu hweasidhi husina kusimba hweacetic acid negallic acid kuti ugadzire uye ugadzire hydrolyze Na2TeO3 kugadzira tellurium dioxide nanoparticle sol, uye uwane tellurium dioxide nanoparticles mumhando dzakasiyana dzekristaro, nehukuru hwezvimedu hunotangira pa200-300nm.
