Ceramic Matrix Composites (CMCs) are redefining the limits of what advanced materials can achieve — from aerospace engines and automotive heat shields to thermal protection systems. Among them, oxide/oxide (Ox/Ox) composites stand out for their exceptional thermal stability, strength, and corrosion resistance. The quality of a final CMC always starts with one critical step: powder and slurry formulation. But how is a slurry formulated for an Ox/Ox CMC of high quality?
💡 What are Baikowski Alumina and Mullite solutions advantages ?
In our latest white paper, we highlight our submicron alumina and mullite powders and show how tailored chemical compositions, dopants (such as nanozirconia), and ready-to-use forms (spray-dried or slurries) can unlock next-generation performance.
Quick technical snapshot
| Material (typical values) | Phase / Purity | d50 | SSA | Notes |
| SM8 (Al₂O₃) | 100% α; high purity | 0.12μm | 10m²/g | Monodisperse PSD; high sintering reactivity |
| BA15-PSS (Al₂O₃ slurry) | 100% α; high purity | 0.11μm | 17m²/g | Stable, low-viscosity, high sintering reactivity. |
| Mullite (3Al₂O₃·2SiO₂) | 100% mullite; high purity | 0.2μm | 35m²/g | Small-sized to enable good densification, compatible with mullite fiber systems. |

📌FAQ — Oxide CMCs (Ox/Ox)
Which alumina is best for Ox/Ox CMC matrices?
Submicron, high-purity α-alumina provides sintering reactivity and stable slurries for Ox/Ox CMC.
Why add nano-zirconia (SLAz) to an alumina matrix for Ox/Ox CMCs?
Uniformly dispersed Mathym’s nano-zirconia (~5 nm) curbs abnormal alumina grain growth during heat treatment and stabilizes the microstructure, preserving matrix mechanical integrity and long-term reliability
What specs matter most in slurry formulation?
PSD, SSA, solids loading, controlled viscosity, slurry stability (in compliance with additives, especially binders /pH/aging)…
