A method is presented for producing hollow microspheres of metal oxides (HMOMS) and/or hollow metal silicates microspheres (HMSMS) in a transforming solution. The transforming solution contains an atom M, or an M-ion, or a radical containing M. M in the transforming solution has the thermodynamic ability to replace silicon atoms in hollow silica microspheres (HSMS) and/or hollow glass microspheres (HGMS). The maximum temperature for transformation is set by the chemical physical properties of the transforming solution, and the viscosity of the silica in the walls of the HSMS and/or the glass in the walls of the HGMS. Viscosity, of enough magnitude, helps retain the desired shape of the hollow sphere as it is transformed to HMOMS and/or HMSMS. Non-spherical shapes can be produced by increasing the transformation temperature whereby the viscosity of the walls of the HSMS and/or the HGMS is reduced. Transformation can take place at a single temperature or at several temperatures, each temperature for a separate hold time. Methods are presented for: 1. production of micro composite castings and continuous production of sheets of micro composites, both consisting of hollow spheres in a matrix, 2. harvesting of HMOMS and HMSMS, and 3. specialty castings for anisotropic properties using 3-dimensional printing.

A lost wax cast vapor chamber device is provided. Once a mesh is produced, a meltable core is formed from a meltable core material with the mesh positioned at least partially inside the core. Over the meltable core a metallic layer is formed, at least partially surrounding the meltable core. A chamber formed by the metallic layer is exposed by melting the meltable core to cause it to be removed from an internal void of the chamber, the internal void encapsulating the mesh. The melted material from the meltable core flows out an opening on at least one surface of the chamber. Subsequently, the internal void is filled at least partially with a working fluid and the opening is closed. The mesh supports the surfaces of the chamber against deformation under the vacuum of the internal void. Movement of working fluid by capillary action is facilitated by the mesh.
