Ceramics, advanced zirconia

Zirconia ceramics represent a fairly new class of advanced stmctural materials (see Zirconium and zirconium compounds). Their potential use in stmctural appHcations was first realized in the mid-1970s. Since then numerous pubHcations have appeared devoted entirely to these materials (76—81). 

Infiltration (67) provides a unique means of fabricating ceramic composites. A ceramic compact is partially sintered to produce a porous body that is subsequently infiltrated with a low viscosity ceramic precursor solution. Advanced ceramic matrix composites such as alumina dispersed in zirconia [1314-23-4] Zr02, can be fabricated using this technique. Complete infiltration produces a homogeneous composite partial infiltration produces a surface modified ceramic composite. 

Ceramics (qv) such as those in Table 12 find high temperature use to over 800°C (32). Advanced ceramics finding interest include alumina., partially stabilized zirconia, silicon nitride, boron nitride, silicon carbide, boron carbide, titanium dibofi.de, titanium carbide, and sialon (Si—Al—O—N) (33) (see...
