Yellow Tungsten Oxide (YTO) Introduction Yellow tungsten oxide is a finely divided, yellow crystalline powder. It is produced by roasting ammonium paratungstate at closely controlled temperatures to drive off water and ammonia. Exact time and temperature control determine, to a large extent, the physical characteristics of yellow tungsten oxide. Yellow tungsten oxide has two colors for different grain size. When the grain size of yellow tungsten oxide is around 1.5um, it shows the color of yellow, and when the grain size of yellow tungsten oxide is around 15um, it shows green. The property is similar. Producing Method Yellow tungsten oxide can be produced by APT calcination method, hydrothermal method, tungstic acid calcination method, precipitation method, sol-gel method, micro emulsion method, spray pyrolysis method, vapor phase method and ion exchange method.

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.
