Strontium hexaferrites has significance role in hexaferrites family. SrFe_12-2xZn_xCr_xO₁₉ (x = 0.0 to 0.5) was synthesized by simplified Sol-gel method. All samples were first calcined and then sintered at 920 °C for 20 min. X-ray Diffracto-meter (XRD) and Scanning Electron Microscopy (SEM) were used to analyze its structural and morphological variations respectively. Microstructural variations were responsible for variations of reported properties. Dielectric constant, loss tangent, loss factor and AC conductivity were determined and discussed as a function of frequency (20Hz to 3 MHz) and dopant. DC resistivity was also measured as a function of temperature up to 600 °C. Parameters like resistivity and activation energy were also discussed. Conduction and polarization mechanism were explained on the basis of Verway Hopping Model, Maxwell Wagner Model and Koop's theory. Substitution of Zn–Cr also affected the ongoing trend. Ranges of both properties obtained are useful against Eddy current losses, devices like Multi-Layer Chip Inductors (MLCI) and other microwave applications.

六价锶锶在六价铁素族中具有重要作用。锶铁_12-2x锌_x铬_x O ₁₉（x ＝ 0.0至0.5）通过简化的Sol-gel方法合成。首先将所有样品煅烧，然后在920°C下烧结20分钟。X射线衍射仪（XRD）和扫描电子显微镜（SEM）分别用于分析其结构和形态变化。微观结构的变化是造成所报告性质变化的原因。确定介电常数，损耗角正切，损耗因子和交流电导率，并将其作为频率（20Hz至3 MHz）和掺杂剂的函数进行讨论。还测量了高达600°C的温度的直流电阻率。还讨论了电阻率和活化能等参数。在Verway跳跃模型，Maxwell Wagner模型和Koop理论的基础上解释了传导和极化机理。Zn-Cr的替代也影响了目前的趋势。
