Siliciumnitrid (Si3N4) tilbyder en af de bedste kombinationer af sejhed og h\u00e5rdhed blandt kommercielt tilg\u00e6ngelige tekniske keramer. Desuden giver den lave varmeudvidelseskoefficient en fremragende modstandsdygtighed over for termisk chok sammenlignet med de fleste andre keramer. Komplekse geometrier kan laves med sintret materiale. Materialet har ogs\u00e5 lav massefylde, styrke ved h\u00f8je temperaturer, fremragende slidstyrke og god sejhed.<\/p>\n

Silicon nitride(Si3N4) offers one of the best combinations of toughness and hardness of commercially available technical ceramics. In addition, its low thermal expansion coefficient offers superb thermal shock resistant compared with most other ceramics. Complex geometries can be made with sintered material. The material also exhibits low density, high temperature strength, excellent wear resistance and… L\u00e6s mere »Siliciumnitrid-keramik<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[10],"tags":[],"class_list":["post-23","post","type-post","status-publish","format-standard","hentry","category-silicon-nitride-ceramic"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
