He teitei ake te pāmahana whakakōkī anō o te waea molybdenum kua tāpirihia ki te lanthanum i te waea molybdenum parakore, nā te mea ka taea e te iti o te La2O3 te whakapai ake i ngā āhuatanga me te hanganga o te waea molybdenum. Haunga tēnā, ka taea hoki e te pānga tuarua o te La2O3 te whakanui ake i te kaha o te waea molybdenum i te pāmahana rūma, me te whakapai ake i te pakarukaru o te pāmahana rūma i muri i te whakakōkī anō.
Whakataurite i te Pāmahana Whakakirikiri Anō: I whānuitia te hanganga moroiti o te waea molybdenum parakore i te 900 ℃, ā, i whakakirikiri anō i te 1000 ℃. I te pikinga o te pāmahana whakamahana, ka piki ake hoki ngā kōpura whakamahana, ā, ka tino heke ngā kiko muka. Ina tae te pāmahana whakamahana ki te 1200 ℃, kua whakakirikiri katoatia te waea molybdenum, ā, e whakaatu ana tōna hanganga moroiti i ngā kōpura whakamahana ōrite. I te pikinga o te pāmahana, ka tipu koretake te kōpura, ā, ka puta he kōpura matotoru. Ina whakamahanahia i te 1500 ℃, ka ngāwari te whati o te waea molybdenum, ā, e whakaatu ana tōna hanganga i te kōpura matotoru ōrite. I whānuitia te hanganga muka o te waea molybdenum kua pania ki te lanthanum i muri i te whakamahana i te 1300 ℃, ā, ka puta te āhua niho ki te rohe o te muka. I te 1400 ℃, ka puta ngā kōpura whakamahana anō. I te 1500 ℃, ka heke tere te kakano o te muka, ā, ka kitea te hanganga kua whakakākanotia anō, ā, kāore i te ōrite te tipu o ngā kakano. He teitei ake te pāmahana whakakākanotanga o te waea molybdenum kua pania ki te lanthanum i tērā o te waea molybdenum parakore, ko te take nui ko te pānga o ngā matūriki wāhanga tuarua o La2O3. Ka ārai te wāhanga tuarua o La2O3 i te hekenga o te rohe kakano me te tipu o te kakano, ā, ka piki ake te pāmahana whakakākanotanga anō.
Te Whakataurite i ngā Āhuatanga Hangarau o te Mahana Rūma: Ka piki ake te roa o te waea molybdenum parakore i te pikinga o te pāmahana whakamahana. Ina tae te pāmahana whakamahana ki te 1200 ℃, ka eke te roa ki te uara mōrahi. Ka heke te roa i te pikinga o te pāmahana whakamahana. Ina whakamahanahia ki te 1500 ℃, ā, tata rite ki te kore tōna roa. He rite te roa o te waea molybdenum kua pania ki te La ki te waea molybdenum parakore, ā, ka eke te tere roa ki te mōrahi ina whakamahanahia ki te 1200 ℃. Kātahi ka heke te roa i te pikinga o te pāmahana. Ko te rerekētanga anake ko te puhoi o te tere whakaheke. Ahakoa ka puhoi te roa o te waea molybdenum kua pania ki te lanthanum i muri i te whakamahana i te 1200 ℃, he teitei ake te roa i te waea molybdenum parakore.
