AI Technical Summary
Existing alumina ceramic preparation processes suffer from high energy consumption, abnormal grain growth, microcracks, and porosity defects, making it difficult to achieve the preparation of dense, high-strength, and highly insulating fuse ceramic shells at low temperatures.
A multiphase synergistic liquid-phase assisted densification sintering and micro-interface control coupling process is adopted. By ball milling and mixing borosilicate glass material, composite grain bridging regulator and composite pore-sealing enhancer, combined with nitrogen-protected sintering, a dense, thermal shock resistant and arc resistant ceramic tube shell is formed.
The ceramic tube shell was densified and its structural stability was achieved at a lower temperature, which improved its mechanical strength and electrical insulation properties and enhanced its resistance to electric arc.
