Ceramic Properties Table and Curves

Product catalog summary

Overview: This document from Dexter Magnetic Technologies Inc. provides detailed specifications and properties of various ceramic magnetic grades. It includes both technical data and graphical representations of magnetic properties.

Magnetic Grade Specifications: The document lists several grades of ceramic magnets, each with specific properties such as Maximum Energy Product (BHmax), Residual Induction (Br), Intrinsic Coercivity (Hci), Coercivity (Hc), Maximum Operating Temperature (Tmo), and Curie Temperature (Tc). All grades have a consistent Curie Temperature of 450°C and a Maximum Operating Temperature of 250°C. The coefficients of induction and coercivity over the temperature range of 20-150°C are also provided, with values of -0.20%/°C and 0.35%/°C respectively.

Typical Physical Properties: The document outlines the typical physical properties of the ceramic materials, including a Curie Temperature range of 450-460°C, Coefficient of Thermal Expansion between +7.0 and +15.0 x 10^-6 °C^-1, Electrical Resistivity greater than 10¹⁰ μΩ·cm, Density ranging from 4.5 to 5.1 g·cm^-3, Vickers Hardness between 480-580 HV, Young’s Modulus of 170 kN·mm^-2, Bending Strength from 0.05 to 0.09 kN·mm^-2, Compressive Strength of 1.3 kN·mm^-2, and Tensile Strength ranging from 0.02 to 0.05 kN·mm^-2.

Graphical Data: The document includes graphs for each magnetic grade, illustrating the relationship between magnetic induction (B) and magnetic field strength (H) at various temperatures. These graphs provide visual insights into the performance of each grade under different thermal conditions.
