This research has, in addition to research in General, is to find the appropriate ratio of expanded pore surface tension reduction additives unless.And thus the burning substance is a 2 step 400° c. To eliminate surface tension reduction on enlarged pores and substance that 800 degrees Celsius.To make alumina crystals.

This research supplements the research generally is the proper proportion of enhanced porous stump surfactant
and the burning of a two-stage at 400 ° C to eliminate the surfactant with enhanced services. Prune and at 800 degrees Celsius
to make alumina is crystalline.
