Two-Step Fabrication of BPO4 Ceramics with Acid Corrosion Resistance and Neutron Shielding Performance

There has been an urgent demand for novel neutron shielding materials (NSMs) with high mechanical strength and low acid corrosion rate to be used in compact design. In this contribution, BPO4 ceramics (BPCs), one of the candidates such materials, was successfully fabricated by a two-step method using H3BO3 H3PO4 as raw materials. The evolution microstructures then investigated, followed testing mechanical/thermal properties, resistance, performance. experimental results indicated that calcination temperature well content intuitively affected densification process BPCs. as-pared BPCs showed reliable properties maximum CMOR, compressive elastic modulus 26.99 MPa, 86.89 MPa 28.42 GPa, respectively, which also 65.11% 0.016%. obtained imply promising NSM use
