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) B2O3 at 1.5 to 5 wt. %, (c) OH at 1000 to 3000 ppm, and (d) B2O3 at 0.5 to 2.5 wt. % and OH at 100 to 1400 ppm. The glass article has an expansivity slope of less than about 1.3 ppb/K2 at 20° C. For DST glass articles doped with F or B2O3, 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: A toy vehicle includes a vehicle body configured for moving along a support surface when disposed in a first orientation. A platform is rotatably coupled to an underside of the vehicle body, and a lever is pivotally coupled to the platform. The lever is movable between a first position disengaged from the support surface and a second position engageable with the support surface when the vehicle is disposed in its first orientation. The lever causes the vehicle to be overturned from its first orientation when the lever is moved from its first position to its second position.

Abstract: A method of making ceramic articles includes compounding ceramic precursor batch components that include hydrous clay. The hydrous clay includes particle components having a platy geometry. The crystallite size of the platy hydrous clay particle components is greater than a predetermined amount. Controlling such crystallite size can result in reduced shrinkage of green ware during the clay dehydroxylation stage of firing.

Abstract: A method of making ceramic articles includes compounding ceramic precursor batch components that include hydrous clay. The hydrous clay includes particle components having a platy geometry. The crystallite size of the platy hydrous clay particle components is less than a predetermined amount. Controlling such crystallite size can result in fired ceramic articles with a lower coefficient of thermal expansion and improved thermal shock resistance.
