Porosity-Controlled Mechanical Behavior in Perlite-Added Pumice Ceramics At 1150 °C

Abstract

This study comparatively examines the effect of 50% perlite addition on phase assemblage, pore architecture, and mechanical behavior in pumice-based ceramic bodies sintered at 1150 °C, against the perlite-free reference P00. Fast-scan XRD (10–90° 2θ) indicates no new crystalline phases in either body and shows coincident peak positions. A semi-quantitative reading via window integration (RIR = 1) reveals phase distributions in both samples of ~55% mullite, ~43% alkali feldspar, and ~1–2% quartz. In contrast, SEM-based morphometry shows that perlite significantly alters the pore architecture: the area fraction of open porosity changes from 60.4 ± 22.3% (P00) to 74.7 ± 6.7% (P50); the median equivalent diameter from 1.46 ± 1.53 µm to 2.46 ± 0.50 µm; the p90 from 5.18 ± 4.03 µm to 20.98 ± 11.50 µm; and the void count from 177 to 49. Archimedes densities are similar (1150-P00: 2.3373 g cm⁻³; 1150-P50: 2.3215 g cm⁻³). Mechanically, the compressive strength in P50 decreases by ~78%, from 36.6 MPa to 8.0 MPa, while microhardness remains statistically equivalent—638 ± 19 HV (P00) vs. 648 ± 24 HV (P50). Additionally, for 1150-P00, SBET ≈ 22.5 m² g⁻¹ and Vp ≈ 0.020 cm³ g⁻¹ were measured. Taken together, the findings indicate that at 1150 °C the phase types are essentially preserved, and the dominant lever on performance is the pore-size distribution and connectivity: a reduced effective load-bearing area lowers compressive strength, whereas the local matrix—retaining its phase/chemical makeup—sustains largely unchanged microhardness.
