2. Conservation and restoration of ceramic objects - Wikipedia

   en.wikipedia.org/wiki/Conservation_and...

   Conservation and restoration of ceramic objects is a process dedicated to the preservation and protection of objects of historical and personal value made from ceramic. Typically, this activity of conservation-restoration is undertaken by a conservator-restorer , especially when dealing with an object of cultural heritage .

3. Lost-foam casting - Wikipedia

   en.wikipedia.org/wiki/Lost-foam_casting

   Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.

4. Ceramic forming techniques - Wikipedia

   en.wikipedia.org/wiki/Ceramic_forming_techniques

   Ceramic shell casting techniques using silica, zirconia and other refractory materials are currently used by the metal parts industry for 'net casting', forming precision shell moulds for molten metal casting. The technique involves a successive wet dipping and dry powder coating or stucco to build up the mould shell layer.

5. Investment casting - Wikipedia

   en.wikipedia.org/wiki/Investment_casting

   Soluble wax cores are designed to melt out of the investment coating with the rest of the wax pattern; ceramic cores are removed after the product has hardened. [6] Assemble wax patterns: Multiple wax patterns can be created and assembled into one large pattern to be cast in one batch pour. In this situation, patterns are attached to a wax ...

6. Polymer derived ceramics - Wikipedia

   en.wikipedia.org/wiki/Polymer_derived_ceramics

   The key advantage of this type of ceramic material is the versatility afforded by the use of polymeric precursors in terms of processing and shaping. Polymer derived ceramics can be additively manufactured (3D printed) by means of fused filament fabrication , [ 4 ] stereolithography that uses photopolymerization of preceramic polymers . [ 5 ]

7. Non-stick surface - Wikipedia

   en.wikipedia.org/wiki/Non-stick_surface

   For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking. It is applied using a sol-gel process without the use of PFAS. [20] The coating layer of ...
