How Carmeltazite is made, mineral harder than diamond

minerals zircon (ZrSiO4) rutile (TiO2) sapphire (Al2O3)
ZrAl2Ti4O11
with covered in quartz so seems silica floats out during melt.

so 1 mole Al2O3
    4 mole TiO2 (is Ti4O8)
    1 mole ZrSiO4

=>

ZrAl2Ti4O11 + SiO2 + O2

Melt with HHO torch.  Cooling rate will determine crystallization.
Even if it breaks apart and pulverizes during cooling, can be used
to coat cutting tools.

Silica should float out during melt and coat the surface. "These corundum minerals are dark
grey to black full with inclusions of mostly titanium, zircon,
aluminum oxides and encrusted by volcanic glass (Griffin et al., 2015)"
