An extruder apparatus for the extrusion of a strand of building material for 3D printing of a structural part includes an extruder nozzle and at least one cover element. The extruder nozzle has a discharge opening for the discharge of the strand of building material out of the extruder apparatus. The at least one cover element is designed to cover at least a part of the discharge opening such that an opening cross section of at least one uncovered part of the discharge opening specifies a strand cross section of the discharged strand of building material.

Provided are a silicotitanate molded body having high strength and reduced generation of fine powder, a production method thereof, an adsorbent comprising the silicotitanate molded body, and a decontamination method of radioactive cesium and/or radioactive strontium by using the adsorbent. The silicotitanate molded body comprises: crystalline silicotitanate particles that have a particle size distribution in which 90% or more, on volume basis, of the particles have a particle size within a range of 1 μm or more and 10 μm or less and that are represented by a general formula of A.sub.2Ti.sub.2O.sub.3(SiO.sub.4).nH.sub.2O wherein A represents one or two alkali metal elements selected from Na and K, and n represents a number of 0 to 2; and an oxide of one or more elements selected from the group consisting of aluminum, zirconium, iron, and cerium.

A method to solidify cremation remains includes milling the cremation remains to a reduced particle size, adding water to the cremation remains to produce a mixture; shaping the mixture into wet ware having a desired shape, drying the wet ware to greenware that is sufficiently dry for firing, and firing the greenware in a kiln until solidified to one or more cremains solids consisting of the cremation remains. A product formed of solidified cremation remains is also disclosed.

A cutting device of cutting a soft honeycomb mold body in a cutting direction perpendicular to an axial direction of the honeycomb mold body. A cutting device has a wire, a tension supply part and a pair of ultrasonic generators. The wire has a contact part which is stretched and in contact with the honeycomb mold body when the honeycomb mold body is cut. The tension supply part supplies tensile to the contact part when the honeycomb mold body is cut. The pair of ultrasonic generators have respective vibrator terminals arranged in contact with the contact part of the wire. The ultrasonic generators generate ultrasonic vibration in the cutting direction and supply the generated ultrasonic vibration directly to the wire.

A method for producing a ceramic molded body, the method including: a molding step of subjecting a ceramic molding material to extrusion molding using an extrusion molding machine equipped with a temperature control portion to provide a ceramic molded body; a cutting step of cutting the ceramic molded body to have a predetermined length; and a dimension measuring step of measure a dimension of the cut ceramic molded body. A relationship between a temperature of the temperature control portion and the dimension of the cut ceramic molded body is previously obtained, and based on the relationship, an appropriate temperature of the temperature control portion is calculated from the dimension of the ceramic molded body measured in the dimension measuring step, and the temperature control portion is controlled to the appropriate temperature in the molding step.
