Aluminum Oxide is very rare, but there is currently a bug in the program that makes it easier to find when playing in Explore mode. To take advantage of this bug do the following:
 * 1) Dig a hole straight down at least 3 blocks deep and drop down the hole.
 * 2) Dig sideways in any direction at least 2 blocks in and walk into the tunnel (tunnel will be 2 block high and at least 2 blocks long).
 * 3) Equip a any material block from your inventory (eg. Exolunar Soil or Basaltic Rock).
 * 4) Look directly below you and place one block. Your head will now be in the block above you.
 * 5) Look up (face forward), the world around you should now be transparent.  If the world is dark (you should still see stars moving in the sky), wait until sun goes below the world and your surroundings will become brighter.  Be sure not to jump after this step or the blocks will appear solid again.
 * 6) When the underground world is bright, look around you.  You should see some black blocks scattered around the underground world.  These are deposits of Aluminum Oxide.  So far they have ranged in size from 1 block to 4 blocks clustered together.
 * 7) Mine towards the nearest Aluminum Oxide deposit.  The world will again become solid, but keep mining in the direction of the deposit.
 * 8) Repeat step 4 when you believe you are nearing the location of the deposit.  This will help you pinpoint its location.
 * 9) Mine the Aluminum Oxide.  Repeat the process to find the next closest deposit.  You will need 16 blocks of Aluminum Oxide to make 1 block of Neptunium.

This bug may be fixed in a future release of Mooncraft, but until then Happy Mining!
