Analysis of fire resistance performance of izitena ze-chrome corundum

Ukusuka kwi-Al2O3-Cr2O3 yesigaba se-binary diagram, sinokubona ukuba i-Al2O3 kunye ne-Cr2O3 inokwenza isisombululo esiqinileyo esiqhubekayo ngaphandle kwe-eutectic. Ngoko ke, ukongeza i-Cr2O3 kwi-high-purity corundum material, kungakhathaliseki ukuba yimali eyongeziweyo, ayiyi kunciphisa kuphela ukuchasana nomlilo wezinto eziphathekayo, kodwa iya kwandisa ukuchasana nomlilo wezinto eziphathekayo. I-refractoriness (> 1790) kunye nobushushu bokunciphisa umthwalo (> 1700!) Izitena ze-chrome corundum zingcono kuneemveliso ze-corundum ezicocekileyo.
