In tegenstelling tot koellichamen op metaalbasis biedt aluminiumoxide keramiek:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Elektrische isolatie<\/li>\n\n\n\n<li>Bestand tegen hoge temperaturen<\/li>\n\n\n\n<li>Corrosiebestendigheid<\/li>\n\n\n\n<li>Stabiele mechanische structuur<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Deze eigenschappen maken het ideaal voor omgevingen waar metalen het kunnen laten afweten als gevolg van geleidbaarheid of oxidatieproblemen.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Belangrijkste voordelen van aluminiumoxide keramische koellichamen<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Elektrische isolatie met thermische stabiliteit<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Alumina keramiek heeft uitstekende di\u00eblektrische eigenschappen, met een volumeweerstand die meestal boven de di\u00eblektrische weerstand ligt. <strong>10\u00b9\u2074 \u03a9-cm<\/strong>, waardoor hij veilig is voor hoogspanningstoepassingen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tegelijkertijd behoudt hij stabiele thermische prestaties bij continu gebruik.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.

Corrosie en chemische weerstand<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In tegenstelling tot metalen oxideert of corrodeert aluminiumoxide keramiek niet gemakkelijk, waardoor stabiliteit op lange termijn gegarandeerd is, zelfs in zware omgevingen zoals vocht, chemicali\u00ebn of vacu\u00fcmsystemen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.
