Sintering crucible for magnetic materials

Sintering Crucible for Magnetic Materials — Product Specification & Description

1. Product Overview

The Sintering Crucible for Magnetic Materials is a high-purity, refractory container specifically engineered for the calcination and sintering of soft ferrites, permanent magnets, and advanced magnetic components. Formulated from premium-grade refractory oxides (such as high-alumina, corundum-mullite, or specialized zirconia-coated matrices), this crucible provides exceptional chemical inertness and structural integrity at elevated temperatures. It shields magnetic raw materials and green bodies from atmosphere turbulence and furnace cross-contamination while ensuring uniform thermal distribution.

2. Key Features & Advantages

• Chemical Inertness & Zero Contamination: High-purity material formulation prevents iron oxide reactions, micro-structural phase shifts, or chemical contamination during high-heat cycles, preserving precise magnetic properties (e.g., permeability and coercivity).

• High-Temperature Structural Stability: Maintains excellent flexural strength and low creep at temperatures up to 1650°C, preventing sagging or cracking under dense loads.

• Exceptional Thermal Shock Resistance: Formulated to withstand continuous thermal cycling in tunnel kilns, pusher furnaces, and atmosphere-controlled batch kilns.

• Non-Stick Surface Coating: Optional high-purity alumina or zirconia surface washes prevent molten phase adhesion or chemical sticking of magnetic powders to crucible walls.

• High Stacking Capacity: Designed with interlocking rims and high cold crushing strength to enable safe multi-tier stacking, maximizing furnace throughput.
