A method performs evaluation of properties of a clay rod, with which a honeycomb structural body is produced. The method mixes raw materials to produce a clay, and extrudes the clay and compresses the extruded clay to produce a clay rod. The method performs NMR to detect at least one of a T1 relaxation time and a T2 relaxation time in each of a normal part and an abnormality part extracted from the clay rod. Each of the T1 relaxation time and the T2 relaxation time corresponds to a relaxation time of nuclear spins of water protons magnetically excited in each of the normal part and the abnormality part. The method performs the evaluation of uniformity of a mixed state and a compression state of the clay rod based on a difference in T1 relaxation time and T2 relaxation time between the normal part and the abnormality part.

A ceramic component, in particular based on zirconia and/or alumina, for a timepiece or jewelry piece, comprising at least one noble metal among platinum, rhodium, osmium, palladium, ruthenium and iridium, at a quantity of less than or equal to 5% by weight.

A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body having volume of 7 L or more; a drying step of drying the manufactured non-fired honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The drying step includes: an induction drying step to obtain a first dried honeycomb formed body by removing 20 to 80% of the entire water that the non-fired honeycomb formed body contained before drying, and a microwave drying step to obtain a honeycomb dried body by removing the residual water. The honeycomb dried body subjected to this microwave drying step is obtained by removing 90% or more of the entire water that the non-fired honeycomb formed body contained before drying.

A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body, the non-fired honeycomb formed body including a raw material composition containing a ceramic raw material and water; an induction drying step of drying the manufactured non-fired honeycomb formed body by induction drying to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The induction drying step is to remove 10 to 50% of the entire water that the non-fired honeycomb formed body contained before drying by induction drying to obtain a first dried honeycomb formed body, then turn the first dried honeycomb formed body upside down and remove the residual water by further induction drying to obtain the honeycomb dried body.

A method for drying at least one unfired columnar honeycomb formed body, the honeycomb formed body comprising a raw material composition containing at least one raw material of ceramics, water and at least one heat-gelling binder, and comprising plurality of cells comprising flow paths penetrating from a first bottom surface to a second bottom surface in an inside of an outer sidewall, the cells being defined by partition walls, the method comprising a step of drying the honeycomb formed body by allowing hot gas satisfying 0.8T2/T13.3 in which T1 represents a gelation temperature of the binder ( C.) and T2 represents a wet-bulb temperature of hot gas ( C.), to pass through the flow paths of the plurality of cells such that the hot gas flows into the first bottom surface and flows out of the second bottom surface, while surrounding an outer side surface of the honeycomb formed body by a correction mold comprising an inner side surface shape corresponding to the outer side surface shape of the honeycomb formed body, wherein during the step of drying the honeycomb formed body, at least a part of the outer side surface of the honeycomb formed body receives pressure from the inner side surface of the correction mold, whereby the honeycomb formed body is subjected to shape correction.

Provided herein are rapid, high quality film sintering processes that include high-throughput continuous sintering of lithium-lanthanum zirconium oxide (lithium-stuffed garnet). The instant disclosure sets forth equipment and processes for making high quality, rapidly-processed ceramic electrolyte films. These processes include high-throughput continuous sintering of lithium-lanthanum zirconium oxide for use as electrolyte films.
