A composition is disclosed comprising a fine zircon component having a median particle size of less than 5 \u03bcm, a medium zircon component having a median particle size of from 5 \u03bcm to 15 \u03bcm, and a sintering aid, wherein the composition, after firing, has a strain rate of less than about 1\xd710\u22126hr. The invention also provides a process for purifying the sugammadex or its pharmaceutically acceptable salts using water and organic solvents. Consequently, it is possible to prevent a viewer from tiring when playing back images mixedly including 2D images and 3D images. The VMI comprises a library of software objects. Therefore, the performance of the safety apparatus can be suitably demonstrated without causing the driver to feel odd. The next bit follows the latched bit in the series of bits.
