The last two of these affect the strength-ductility balance, which is
frequently optimized in materials design; the objective being to increase both strength and ductility
simultaneously.

Activated material is sieved with 140 mesh sieve.
Material printed manually shaped tube.
These materials are printed in the form of tubes which are then carried out combustion at varied temperatures namely 600 oC, 700 oC and 800 oC for 6 hours.
This happens because of the large number of zeolite compositions used in membrane-forming materials which results in the formation of more pores.
