Yellow Tungsten Oxide SEM Micrograph Yellow tungsten oxide is a tungsten oxide which molecular formula is WO3. Its colors vary from its particle sizes. When the crystal size is about 1.5 um, it is yellow. When the crystal size is about 15 um, it is green. The appearances are different, but the characteristics are similar. Yellow tungsten oxide has many uses in our daily life. It is often used to product fireproof fabric of X ray screen phosphor, gas sensor and tungstate. Because of its bright yellow, yellow tungsten oxide is also used as a pigment in paints and ceramics. Scanning electron microscope (SEM) is a kind of scanning equipment used for micrograph by multiplying objects, which can be metal, powder, etc. From the following SEM micrographs, the morphology structures are obviously different with different synthesis methods.

Yellow Tungstan Ocsaíd (YTO) Réamhrá Is ocsaíd saoirsithe Buí mín roinnte, púdar criostalach buí. Tá sé a tháirgtear trí róstadh paratungstate amóiniam ag teochtaí rialaithe dlúth a thiomáint as uisce agus amóinia. am cruinn agus rialú teochta a chinneadh, go mór, tréithe fisiciúla na ocsaíd saoirsithe buí. Tá ocsaíd tungstain Buí dhá dhath le haghaidh méid gráin éagsúla. Nuair a bhíonn an méid gráin na ocsaíd tungstain buí timpeall 1.5um, taispeánann sé an dath buí, agus nuair a bhíonn an méid gráin na ocsaíd tungstain buí timpeall 15um, taispeánann sé glas. Is é an mhaoin den chineál céanna. Modh táirgthe Is féidir le ocsaíd tungstain Yellow a tháirgeadh trí mhodh APT calcination, modh hydrothermal, modh calcination aigéad tungstic, modh deascadh, modh Sol-fhoirmiú, modh eibleacht micrea, modh pirealú spraeála, modh chéim gal agus modh malartaithe ian.
