| titleOfInvention | Method of making blocks of PbxMoySz in the Chevrel phase |
| abstract | The invention relates to a process for the production of blocks from Pb x Mo y S z chevrel phases, where x = 0.9 to 1.2, y = 6.0 to 6.4 and z => to 8, in which powder from the elements and / or from the corresponding metal sulfides as starting materials, after thorough mixing, are subjected to an isostatic hot pressing process at a temperature in the range from 800 ° C. to 1200 ° C. and a pressure of more than 10 MPa (> 100 bar).n n n 1) kg-Mengen der gemischten Ausgangsmaterialien in ein metallisches Behältnis eingebracht werden, 2) danach das Behältnis bis zu einem Druck ≦10⁴ Pa evakuiert wird, 3) das evakuierte Behältnis mit dem Pulvergemisch bei einem während des ganzen Vorganges konstant gehaltenen Druckes im Bereich von 100 MPa bis 300 MPa bei Aufheizraten im Bereich von 10° C/h bis 1000° C/h und bei einer Temperatur im Bereich von 800° C bis 1200° C heißgepreßt wird, wobei die Ausgangsmaterialien zur Chevrel-Phase reagieren, und 4) nach einer Haltezeit des Druckes und der Endtemperatur im Bereich von 10 Stunden bis 100 Stunden, abhängig von der eingebrachten Pulvermenge, der erhaltene Block mit einer Abkühlrate im Bereich von 50° C/h bis 500° C/h kontrolliert bei konstant beibehaltenem Druck abgekühlt wird. Since a high density of the chevrel phase block, a uniform, largely single-phase composition, and a density that extends uniformly through the block are no longer guaranteed when processing increasing amounts of starting materials, it is an object of the invention to provide a method for producing largely single-phase blocks of these To create species with a high density of ≧ 90% of the theoretical density in kg quantities, which are homogeneous, free of gas bubbles and without density gradient. This is achieved in that 1) kg quantities of the mixed starting materials are placed in a metallic container, 2) the container is then evacuated to a pressure of ≦ 10⁴ Pa, 3) the evacuated container with the powder mixture at a constant pressure throughout the entire process in the range from 100 MPa to 300 MPa at heating rates in the range from 10 ° C / h to 1000 ° C / h and at a temperature in the range from 800 ° C is hot pressed to 1200 ° C, the starting materials react to the Chevrel phase, and 4) after a holding time of the pressure and the final temperature in the range from 10 hours to 100 hours, depending on the amount of powder introduced, the block obtained with a cooling rate in the range from 50 ° C./h to 500 ° C./h is controlled with the pressure kept constant is cooled. |
