Read the following technical passage:
High-altitude transport aircraft utilize catalytic ozone converters to decompose atmospheric ozone entering the environmental control system before it reaches the passenger cabin. The converter core is composed of a ceramic honeycomb matrix wash-coated with a noble metal catalyst, primarily palladium and platinum. At normal cruise altitudes, ambient bleed air passes through the matrix at temperatures exceeding 150 degrees Celsius. The catalytic reaction breaks down toxic ozone into diatomic oxygen without consuming the precious metal coating. If the core becomes contaminated with silicone vapors, the catalyst surface undergoes irreversible poisoning, requiring immediate solvent degreasing and ultrasonic bath cleaning to restore baseline efficiency.
