Ca–Al co-doped strontium hexaferrite powder with a cation composition of Sr_0,54Ca_0,46Fe_6,5Al_5,5O₁₉ was synthesized using solid-state route. The prepared powder was calcined at different temperatures (1200 °C, 1250 °C, 1300 °C and 1350 °C) for 24 h. Structural, morphological and magnetic properties of synthesized samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and SQUID measurements. The XRD results confirmed the hexagonal structure. The calcination temperature sufficient for the complete formation of the phase was found to be 1300 °C. The size of the crystallite determined from XRD data was found to be small compared to that of the grain size calculated from the SEM micrograph. According to the magnetic data, an increase in the calcination temperature leads to a small increase in the remanent magnetization and coercivity field. This can be explained by the increase of the crystallite size.

钙铝共掺杂的六方晶系铁氧体锶粉末与Sr的阳离子组成_0,54的Ca _0.46铁_6,5的Al _5,5- Ô ₁₉采用固态途径合成。制备的粉末在不同温度（1200℃、1250℃、1300℃和1350℃）下煅烧24小时。通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和 SQUID 测量研究合成样品的结构、形态和磁性。XRD结果证实了六方结构。发现足以完全形成相的煅烧温度为 1300°C。发现由 XRD 数据确定的微晶尺寸与由 SEM 显微照片计算的晶粒尺寸相比较小。根据磁性数据，煅烧温度的增加导致剩磁和矫顽力场的小幅增加。这可以通过晶粒尺寸的增加来解释。
