A Gas Pressure Sintering Furnace for Structural Ceramics
Abstract
The grant was initiated on February 1, 1998. A no-cost extension for one year was requested in January 1999. We have designed, purchased and received a gas pressure sintering furnace from Centorr Inc. (Model 2723EP). This furnace is in full operation. We have proceeded with the proposed research on the in-situ toughened a -SiAlON and on the synthesis of high b-content Si3N4 powders. We have also purchased, received and tested a cold isostatic press from ABB Autoclave (CIP 42260). This equipment is also in operation in the laboratory. Since funds were used from University sources to advance the payment of the gas pressure sintering, we have used the residue funds to purchase characterization equipment for a' -SiAlON research. The new equipment has been delivered and has allowed characterization of a'-SiAlON, especially the mechanical properties (R-curve, creep, and high temperature strength) to be carried out in our laboratory.
