In order to research the toughening effects of carbon nanotubes on 3Y-ZrO2 via different moulding methods. 3Y-ZrO2 and 3Y-ZrO2 with two kind of carbon nanotubes were prepared by compression moluding forming and gel-casting. And all of the green bodies were sintering at 1600°C in high temperature furnace. The X-ray diffraction and density of sintered bodies, microstructural of fracture surface and fracture toughness were characterized and analyzed. Results shown that gel-casting is better than compression about toughening 3Y-ZrO2 by carbon nanotubes. For gel-casting, the density is nearly the same and fracture toughness has been improved which is form 5.17MPa·m1/2 to 5.63 MPa·m1/2. For compression moulding forming, the density was reduced by the aggregation of carbon nanotubes. The fracture toughness can’t improve by carbon nanotubes.

Temperature Furnace

A complex high-temperature furnace has been produced from presintered α-Al2O3precompacts. The furnace is designed for the Mar345 imaging-plate detector system. Up to now, the design complexity of ceramic parts has been limited by the difficulty of machining hard ceramic materials or by the moulds used in hot-pressing and casting. However, the machining of soft presintered ceramic materials enables the realisation of much more demanding designs, provided that the final sintering shrinkage of the ceramic is homogeneous and predictable. The design of the furnace and its realisation and application in an X-ray diffraction study with synchrotron radiation are presented.

Temperature Furnace

A high-temperature furnace with an induction heater coil and a cryogenic system based on closed-cycle refrigeration have been assembled to enhance the non-ambient powder diffraction facilities at the Synchrotron Radiation Source, Daresbury Laboratory. The commissioning of the high- and low-temperature devices on the high-resolution powder diffractometer of Station 2.3 is described. The combined temperature range provided by the furnace/cryostat is 10–1500 K. Results from Fe and NH4Br powder samples are presented to demonstrate the operation of the apparatus. The developments presented in this paper are applicable to a wide range of other experiments and diffraction geometries.
