Description
dvb≦1.10、dvb≦1.00、またはdvb≦0.90によって特徴付けられる。ここで、dvb=(dv90−dv10)/dv50である。気孔サイズ分布の大きい気孔と小さい気孔との双方を管理することは、背圧を低下させるのみでなく、例えば、FE0≧50%、FE0≧70%、またはFE0≧90%もの素晴らしい濾過効率をも提供する。10.0μm未満の中央気孔径に組み合わされたこのような極めて狭い気孔サイズ分布を提供することは、別の広範な効果において、再生時におけるピーク温度を低下させて、耐久性の向上に寄与する。
TSL=TSP+500℃
TSP=MOR/{[E−mod][CTEH]}
歪み許容度=MOR/E−mod
ここで、RTは室温(25℃)を表し、
E−modはセル構造の25℃における弾性係数であり、
MORは25℃における破壊強度係数(psi)であり、かつ
CTEHは、500℃と900℃との間で測定された高温熱膨張係数である。MOR、E−modおよびCTEHは、全てセル構造を有するサンプル上において、チャンネルの長さ方向と平行な方向に、すなわち軸線方向に測定された。破壊強度係数(MOR)は、4×1×1/2インチ(10.2×2.5×1.3cm)の寸法を有する長方形のバー上で4点法により軸線方向に測定された。さらに、本発明の実施の形態は、比較的低い圧力低下(ΔP、クリーン時および煤負荷時)と結び付けられた比較的高い初期濾過効率(FE0)との好ましい組合せを示す。
比較的低い圧力低下(ΔP)と結び付けられた比較的高い初期濾過効率(FE0)を必要とするセラミックフィルタの用途に対して最も有用である。本発明のハニカムの壁の一部分の微細構造を表す軸線に方向から見た断面の50倍、250倍、および500倍の顕微鏡写真が、図5〜図7にそれぞれ示されている。このようなセラミック物品は、排気微粒子フィルタの用途等の微粒子物質の濾過に特に良く適しており、かつこのような用途において高い耐熱性を提供する。
dv90≦12.0μm、dv90≦11.0μm、またはdv90≦10.0μmをも備えている。実施の形態のさらなる特徴付けによれば、dv10≧2.0μmおよびdv10≦12.0μmによって特徴付けられたような、極めて狭い気孔サイズ分布が達成される。このような極めて狭い気孔サイズ分布は、25℃から800℃までにおいて少なくとも一方向に測定されたCTE≦12.0×10−7/℃をさらに備えながら達成される。
dvb=(dv90−dv10)/dv50
このため、他の幅広い態様における多孔質コージェライト・セラミック構造は、dvb≦1.50である。具体的な実施の形態によっては、dvb≦1.30またはdvb≦1.20である。本発明による極端に狭い気孔サイズ分布はdvb≦1.00またはdvb≦0.80を示すかも知れない。多くの実施の形態はdvb≦1.00と4.0μm≦dv50≦10.0μmとの組合せ、またはdvb≦0.80と4.0μm≦dv50≦10.0μmとの組合せが望ましい。
