Annotatsiya. Kirish. Sintez usuli ma’lum zarracha o‘lchami, tuzilishi, mikro tuzilishi va o‘ziga xos sirt maydoni va faza barqarorligiga ega bo‘lgan materialni olishda muhim rol o‘ynaydi. Ushbu parametrlar birgalikda ma'lum xususiyatlarni aniqlaydi. Asosiy sintez usullari: qattiq fazali reaksiyalar, termik parchalanish, gidrotermik va solvotermik usullar, birgalikda cho‘ktirish, sol-gel va mikroto‘lqinli ishlov berish. Biroq, har bir usul o‘zining afzalliklari va kamchiliklariga ega va shpineldan yuqori sifatli ferrit materiallarini olishning optimal usuli yo‘q. Shuning uchun quyosh pechida Fe2O3 + NiO aralashmasi eritmasidan sintez qilingan NiFe0O4 nikel ferritining tuzilishi va xususiyatlarini o‘rganish.Usullar va materiallar. Aralash agat ohakchasida etil spirti (10 og‘irlik) qo‘shilgan holda maydalangan va diametri 12 mm va balandligi 15 mm bo‘lgan tabletkalarga solingan. Tabletkalar quyosh pechining diametri 30 mm bo‘lgan doira shaklidagi markazlashtirilgan nuqtada joylashgan eritish stoliga qo‘yildi. Eritma suvga quyilishi bilan sovutilgan. Qattiqlashtirilgan quymalar 1100 °C da maydalangan, qoliplangan va sinterlangan. Natijalar. 8,87 Å panjara parametri bilan nikel ferrit NiFe2O4 ning kubik modifikatsiyasini ifodalovchi bir fazali material olindi. Yangi sintez qilingan material Hc=60 Oe, Ms=30 emu/g parametrlari bilan yumshoq magnit xarakterga ega bo‘ldi. 1100 °C da pishirilgan material Hc = 80 Oe, Ms = 50 emu / g ko‘tarilgan parametrlarni ko‘rsatdi.
Xulosa. Quyosh pechida eritmadan sintez yo‘li bilan olingan material tuzilishi va magnit parametrlari tufayli organik xom ashyoni isloh qilish orqali vodorod sintezining katalitik jarayonlarida qo‘llanilishi mumkin.
