While preparing LaMgAl11o19 powder for FG-TBC, which type of powder synthesis should be followed?

1) La2o3 heated 1100C for 5h previously and three powders are ball milled for 3h and dried for 70c

2) Three powders mixed at 1650C for 24h and ball milled with arabic gum and deionized water and spray dried

Which of these is the better process? Please tell me if any other procedure are better.

You can try autoignition route. Where chemicals are taken in nitrate and chloride and added some fuel like citric acid. After ignition you get some powder. These powder if you calcine at around 1000 C you will get very fine grained even nano sized powder
