Abstract
يتم الترسب الكهرلي للغشاء الرقيق من نوع mnpo4، h2o انطلاقا من محلول مائي يحتوي على 0,2m من سولفات المنغنيز؛5m من حامض الفوسفوريك. يتم انجاز ترسبه الكهرلي من خلال الأكسدة الغالفانية الثابتة.يجري تفاعل الترسب الكهرلي في مرحلتين: الأكسدة الكهروكيميائية ل mn(ii) إلى mn (iii) متبوعة بعملية ترسيب في بيئة فسفورية (m5).تتم دراسة تأثير متغيرات التوليف على تحضير فيلم رقيق من نوع mnpo4، h2o ،.البنية البلورية للترسبات المدروسة من خلال حيود أشعة إكس x تم ربطها بشكل سليم بالبنية ذات الشكل المنشوري المائل mnpo4، h2o .الدراسة المورفولوجية تم انجازها بالمجهر الإلكتروني الماسح وكشفت عن سطح مسامّي. تم حساب حجم البلورات الدقيقة بواسطة معادلة "شيرير" scherrer.الكلمات المفتاحة: mnpo4، h2o ؛مواد نانوية-متناهية الصغر؛ طبقات رقيقة؛ أنودية؛ حيود أشعة x ؛ المجهر الإلكتروني الماسح؛ مطياف الأشعة تحت الحمراء.The electrolytic deposition of the thin film is of the type mnpo4, h2o from an aqueous solution containing 0,2m of manganese sulfate; 5 m of phosphoric acid. The electrolytic reaction is carried out in two phases: the electrochemical oxidation of mn (ii) to mn (iii) followed by a deposition in a phosphorous environment (m5). The crystalline structure of the sediments studied by x-ray diffraction has been properly correlated with the diagonal prism-shaped structure mnpo4, h2o. The size of the fine crystals was calculated by the scherrer equation; mnpo4, h2o; nanomaterials; thin layers; anodic; x-ray diffraction; scanning electron microscopy;
