    Abstract: Composite ceramic materials are disclosed herein which comprise two or more crystalline phases, wherein a first crystalline phase comprises a first refractory material having a first melting point, and a second crystalline phase comprises a second refractory material having a second melting point which is lower than the first melting point, and the second crystalline phase comprises large domain sizes of the second refractory material. Articles comprising such a composite ceramic material, such as honeycomb bodies, catalytic substrates, and particulate filters, are also disclosed herein, in addition to methods of manufacture thereof.

    Abstract: A doped silica-titania ("DST") glass article that includes a glass article having a glass composition comprising a silica-titania base glass containing titania at 7 to 14 wt.% and a balance of silica, and a dopant selected from the group consisting of (a) F at 0.7 to 1.5 wt.%, (b) B 2 O 3 at 1.5 to 5 wt.%, (c) OH at 1000 to 3000 ppm, and (d) B 2 O 3 at 0.5 to 2.5wt.% and OH at 100 to 1400 ppm. The glass article has an expansivity slope of less than about 1.3 ppb/K 2 at 20°C. For DST glass articles doped with F or B 2 O 3 , the OH level can be held to less than 10 ppm, or less than 100 ppm, respectively. In many aspects, the DST glass articles are substantially free of titania in crystalline form.

    Abstract translation: 掺杂二氧化硅 - 二氧化钛（“DST”）玻璃制品，其包括玻璃制品，所述玻璃制品具有包含二氧化钛 - 二氧化钛基玻璃的玻璃组合物，所述二氧化钛 - 二氧化钛基玻璃含有7重量％至14重量％的二氧化钛， 二氧化硅和掺杂剂，所述掺杂剂选自（a）0.7至1.5重量％的F，（b）1.5至5重量％的B 2 O 3， ％，（c）1000-3000ppm的OH，和（d）0.5-2.5wt％的B 2 O 3和100-1400ppm的OH。 玻璃制品在20℃下的膨胀率斜率小于约1.3ppb / K 2。 对于掺杂有F或B 2 O 3的DST玻璃制品，OH水平可分别保持在小于10ppm或小于100ppm。 在许多方面，DST玻璃制品基本不含结晶形式的二氧化钛。
