Tabla Corundum yog cov sinta ntshiab alpha colra corundum cov ntaub ntawv, uas yog lub cev ntom nti sai sai sintereded ntawm qhov kub siab dua 1900 degree yam tsis muaj Sintering AIDS. Nws zoo heev thermal ntim stability thiab thermal poob siab kuj tuaj yeem raug ntaus nqi rau qhov tshwj xeeb microstructure ntawm tabular corundum: ob peb qhib qhov hws, muaju loj, thiab kaw lub qhov pores uas raug kaw los ntawm recrystallization thaum sintering ceev. Yog li dab tsi yog qhov kev taw qhia thiab cov khoom ntawm tabular corundum?

Tabular corundum qhia:
Tabular corundum muaj cov cua kub tsis tshua muaj siab, txhua yam muaj zog thiab hnav tsis kam, tshuaj purity siab, zoo rwb thaiv tsev zog, thiab zoo acid thiab alkali corrosion kuj.
Tabular corundum yog qhov zoo tshaj plaws sib sau ua ke rau amorphous thiab zoo li tus refractories siab thiab yog dav siv hauv steel, foundry, petrochemical, ceramics thiab incineration industries. Lwm daim ntawv thov muaj xws li hluav taws xob insulators, kiln rooj tog thiab catalyst txhawb nqa. Av tabular corundum hmoov yog ib yam khoom zoo heev rau kev siv los ua cov khoom siv hauv epoxy resins lossis resin systems, qhov siab dielectric lub zog, thermal conductivity thiab abrasion kuj xav tau.
Tabular corundum zog:
1. Ntsuas qhov hnyav. Qhov ntau ntom ntawm tabular corundum hais txog qhov hnyav ntawm cov khoom ib chav tsev ntim hauv lub xeev ntuj. Feem ntau, tabular corundum nrog ib qho loj me me yog qhov zoo rau kev tawg hauv electrolyte.
2. Granularity. Qhov loj me me ntawm tabular corundum hais txog nws qhov tuab. Qhov loj me me ntawm tabular corundum yuav tsum tsim nyog. Yog hais tias nws yog ntxhib heev, nws yuav yaj maj mam nyob rau hauv cov electrolyte, los yog txawm precipitate; yog nws zoo heev, nws yuav yooj yim ya thiab poob.
3. Cov cheeb tsam tshwj xeeb. Qhov tshwj xeeb ntawm thaj chaw ntawm tabular corundum yog hais txog tag nrho qhov chaw saum npoo ntawm qhov sib npaug ntawm thaj chaw sab nrauv thiab sab hauv qhov pore nto ntawm cov khoom hauv ib chav tsev qhov hnyav. Nws yog ib qho tseem ceeb qhia txog qib kev ua ntawm ib yam khoom. Tabular corundum nrog thaj chaw loj tshwj xeeb muaj qhov zoo solubility hauv electrolyte thiab kev ua haujlwm siab, tab sis nws yooj yim rau nqus dej noo.
4. Hnav yam. Lub npe hu ua coefficient yog qhov feem pua hloov pauv ntawm cov ntsiab lus me me hauv cov qauv tom qab tabular corundum yog hauv av thiab sib tsoo ntawm lub txaj fluidized raws li kev tswj xyuas. Qhov hnav coefficient yog qhov ntsuas lub cev uas qhia lub zog ntawm tabular corundum.
