When a crack grows through the ceramic,the zirconia particles rystal structure in the region of the crack changes from the metastable tetragonal phase to the stable monoclinic phase.The change increases the volume of the particles by about 3-4% and produces compressive stresses in the alumina matrix. These stresses in turn close the crack and act as an energy barrier to further crack growth. The addition of zirconia to the alumina matrix increases fracture toughness by two times and can be improved by as high as four times, while [&hellip;]<\/p>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"ngg_post_thumbnail":0,"footnotes":""},"class_list":["post-45","page","type-page","status-publish","czr-hentry"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/pages\/45"}],"collection":[{"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/comments?post=45"}],"version-history":[{"count":6,"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/pages\/45\/revisions"}],"predecessor-version":[{"id":53,"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/pages\/45\/revisions\/53"}],"wp:attachment":[{"href":"https:\/\/zirconia-ceramics.com\/ja\/wp-json\/wp\/v2\/media?parent=45"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
