It is Yes, you can use gamma alumina as a precursor to synthesize magnesium aluminate via mechanical milling using agate grinding jars. However, the hardness of the alumina may affect the agate grinding jar.
Agate grinding jars are commonly used in mechanical milling due to their high wear resistance and low contamination. However, they can be scratched or damaged by hard materials, such as gamma alumina, which has a hardness of around 8.5 on the Mohs scale.
To minimize the potential damage to the agate grinding jar, it is important to use the appropriate milling parameters, such as the milling speed, ball size, and ball-to-powder ratio. Additionally, it may be helpful to periodically inspect the agate jar for signs of wear or damage and to replace it if necessary.
It is very important to say, while gamma-alumina can be used as a precursor to synthesize magnesium aluminate via mechanical milling with agate grinding jars, it is important to consider the potential impact of the alumina's hardness on the agate jar and take appropriate precautions to minimize any damage.
Hope you can fins what you want
