The spinel ZnFe2O4 specimens were obtained via a hydrothermal and ceramic method, respectively, their structural magnetic properties comparatively studied. It was found that all the exhibited single-phase mixed structure. magnetism of synthesized method is obviously better than specimen prepared method. This can be ascribed to different occupancy Fe ions resulted from loss Zn during process.

Trong nghiên cứu này, vật liệu nano ZnFe2O4 được tổng hợp thành công bằng phương pháp thủy nhiệt kết với nung. Các yếu tố ảnh hưởng đến quá trình như thời gian nhiệt, độ và nung đã khảo sát. Vật đặc trưng nhiễu xạ tia X (XRD), hiển vi điện tử quét (SEM), phổ hồng ngoại (FT-IR) hấp phụ/khử phụ ni tơ (BET). Kết quả cho thấy tinh thể spinel có trật tự cao ở 120 °C, 24 h 500 °C.
