The honeycomb structural body includes the honeycomb unit including plural cells extending from a first end face to a second end face in a longitudinal direction. The plural cells are partitioned by cell walls. | 05-19-2011 |

| 20140117594 | Ceramic Precursor Batch Compositions For Increased Tonset Using Organic Additive Heteroatom Polyols - A ceramic precursor batch composition comprising inorganic ceramic-forming ingredients, a binder, an aqueous solvent and a heteroatom polyol agent. The heteroatom polyol agent can be represented by X(R) where X is at least one of S, N, and P, and R is at least two of CH | 05-01-2014 |
| 20140252695 | FAST FIRING METHOD FOR CERAMICS - A method for firing a green honeycomb ceramic body in a kiln may include heating the green honeycomb ceramic body in four stages. The first stage may include heating the green honeycomb ceramic body from room temperature to a first temperature that at a first heating rate that is greater than or equal to about 75° C./hr. The second stage may include heating the green honeycomb ceramic body from the first temperature to a second temperature at a second heating rate that is less than or equal to the first heating rate. The third stage may include heating the green honeycomb ceramic body from the second temperature to a hold temperature at a third heating rate that is less than or equal to the first heating rate. The fourth stage may include holding the green honeycomb ceramic body at the hold temperature to remove residual carbon. | 09-11-2014 |

The green honeycomb ceramic body is then heated from the first temperature to a second temperature of greater than or equal to about 800° C. at a heating rate of greater than or equal to about 90° C./hr. The green honeycomb ceramic body may have a diameter of from greater than or equal to about 4.0 inches to less than or equal to about 9.0 inches, and it may include a carbon-based pore former in a concentration of from greater than or equal to about 10% to less than or equal to about 45% by weight. | 01-29-2015 |
| 20150028528 | FAST FIRING METHOD FOR HIGH POROSITY CERAMICS - A method for firing a green honeycomb ceramic body including heating the green honeycomb ceramic body from room temperature to a first temperature of less than or equal to about 350° C. with at least one heating rate of greater than or equal to about 80° C./hr. The green honeycomb ceramic body may be heated from the first temperature to a second temperature of greater than or equal to about 800° C. at a heating rate of greater than or equal to about 90° C./hr. The green honeycomb ceramic body may be heated from the second temperature to a third temperature of greater than or equal to about 1000° C. The green honeycomb ceramic body may include aluminum raw materials for forming an aluminum titanate ceramic body. | 01-29-2015 |
