Working with TiO2 Ceramic 95
Is TiO2 Ceramic easy to machine?
Green/bisque machining is the economical route; fired titania needs diamond grinding, EDM is impossible for the insulating grades (possible on reduced conductive TiOx).
Can TiO2 Ceramic be welded?
Not weldable — joined by glass frit, active-brazing (Ti/Ag-Cu ABA) or ceramic adhesive; metallise with Mo-Mn+Ni for hermetic seals.
Can TiO2 Ceramic be formed, bent or molded?
Dry pressing, isostatic pressing, extrusion or tape casting of doctor-bladed slurry; sinter 1250–1500 °C in air with slow cooling to keep stoichiometry.
What surface finishes work on TiO2 Ceramic?
Lap and diamond-polish for flatness/optical work; avoid reducing furnace atmospheres or firing on carbon setters, which blacken the surface and kill insulation resistance.
