摘要： A composition comprises at least one form of attapulgite present in a solid weight fraction amount ranging from 0.25% to 5%; kaolin present in a solid weight fraction amount ranging from 17% to 50%; and optionally Ball Clay in a solid weight fraction amount ranging from 0% to 25%. Although makeable by other processes, in some embodiments, the composition is makeable by mixing component ingredients. Although usable for other purposes, in some embodiments, the composition is used to make ceramic pieces, e.g., via casting, pressing, jiggering or jollying, especially when the slip has solids, chemistry and viscosity suitable for shaping before drying, sintering, and optionally finishing.

摘要： 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, 0.5 to 5.0 mass % of pore former 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 20 to 80% 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.

摘要： Systems and methods for rapid drying of ceramic greenwares having a high graphite content are disclosed. The methods include employing microwave drying to bring the dryness of the ceramic greenware to a first select dryness and then employing close-coupled hot-air drying to bring the dryness to the final target dryness. The judicious use of close-coupled hot-air drying reduces end defects due to unevenness in the microwave drying process while also substantially speeding up the drying process. Various configurations for and combinations of microwave drying and close-coupled hot-air drying are disclosed.

摘要： Method and apparatus for quickly drying shaped ceramic bodies (3) having a complex surface (3a, 4a) with enriched unevenness, and a simple surface (3b, 4b) which is less uneven as compared to the complex surface (3a, 4a), without causing drying cracks and within a shortened time. The shaped ceramic body (3) within a drying chamber (1) is primarily heated from the simple surface (3b, 4b) by a main infrared heater (6), which is arranged on the simple surface side. Preferably, the ceramic body (3) is also heated by an auxiliary infrared heater (7) of a relatively low temperature, which is arranged on the side of the complex surface (3a, 4a), or dried while admitting a hot air into the drying chamber (1) with a low speed.

摘要： A process for dielectric-drying a honeycomb structure is carried out by placing the honeycomb structre on a drying support board provided with perforated plates, and directing an electric current between an electrode arranged above the upper opening end face of the honeycomb structure and an electrode arranged beneath the lower opening end face thereof to conduct the drying. In this process, an upper plate having a conductivity higher than that of the honeycomb structure is placed on the upper opening end face of the honeycomb structure.
