Honeycomb Ceramics

Honeycomb Ceramics

Emissions control solutions are critical for reduction of greenhouse gases and particulates from sources such as mobile vehicles and stationary power plants.  Global energy consumption is expected to rise over 50% in the next 30 years and the number of vehicles on the roadways will soon  exceed 90 million.  While these numbers are only expected to increase, particularly in developing areas, environmental regulations are getting tighter.

Honeycomb ceramics are typically used as substrates that are coated with a catalyst for emissions control purposes. Substrate consistency is necessary for the coating process, both to ensure adequate emissions regulation and because of the high value associated with precious metals being used.

Almatis aluminas for honeycomb ceramic applications include batch and continuous ground products.  Our fine crystalline aluminas are ground in batch ball mills to provide a narrow particle size distribution for use as the fines component of a mix or as a standalone component in a high performance product.

Our coarse crystalline aluminas are continuous ground in ball mill – air classifier systems to provide a broad distribution with minimal +45µm agglomerates. The strict controls we place on our process ensures a consistent product for making reproducible, high quality substrates.
