Abstract:
A mold and a method of manufacturing GOS ceramic scintillator by using the mold are provided. The mold comprises: a female outer sleeve (101) having a cavity disposed inside; a plurality of female blocks (302) disposed inside the cavity, the plurality of female blocks being put together to form a composite structure having a vertical through hole; and a male upper pressing head (303) and a male lower pressing head (304), wherein each of the male upper pressing head and the male lower pressing head has a shape consistent with that of the vertical through hole. The disclosure may reduce defects of the related art in hot-pressing-sintering such as a mold has a short retirement period and a high material waste, significantly reduce the cost for production of the GOS ceramic scintillator, and significantly improve a process economy.

Abstract:
Problem: To provide a cutting tool formed from a silicon nitride-based sintered body having high fracture resistance and having residual stress of a rake face and a flank face in an appropriate range. Solution: A cutting tool (1) formed from a silicon nitride-based sintered body containing not less than 50 volume % silicon nitride-based phase and from 10 to 30 volume % titanium nitride phase, uses an intersection ridge portion of a rake face (2) and a flank face (3) as a cutting edge (4), has a residual stress applied to the titanium nitride phase that is tensile stress, and is such that the tensile stress applied to the titanium nitride phase in the rake face (2) is greater than the tensile stress applied to the titanium nitride phase in the flank face (3).
Abstract:
A method of forming a nanoscale ceramic composite (100) generally includes modifying a polymeric ceramic precursor, mixing the modified polymeric ceramic precursor with a block copolymer to form a mixture, forming an ordered structure from the mixture, wherein the modified polymeric ceramic precursor selectively associates with a specific type of block of the block copolymer, and heating the ordered structure for a time and at a temperature effective to form the nanoscale ceramic composite (100). Also claimed are the nanoscale composite formed by the method, a polycarbosilane and a method of modifying a polycarbosilane.
