Interesting Result of Al2O3 project

Kneading of a clear body of Arg. was started in the morning without fibers.

Al₂O₃ fiber is not broken this time. So discussed with the supervisor and checked the fiber under the microscope. It could be seen that still the core has not removed completely but the burnt carbon is remaining. It is quite difficult to make sure whether carbon is there only as a layer or a solid part. Hence, the fiber will be examined under the light microscope and photographed.

Kneading was done for five hours and then the cleaning of the machine. It was very hard to clean the machine as usually happened last times. There was an idea to use MH material to do an over extrusion so that the whole part of Arg. body will come out. But this time only an abrasive liquid was used and it took about 3.30 hours to finish the cleaning.

Another sample was put to the furnace and this time the final temperature will be little bit higher maintaining the previous ramps.
