De kleur van korund is wit. In veel gevallen kan de kwaliteit van de korundsteen alleen worden vastgesteld aan de hand van de kleur van de korundsteen. Veel klanten zullen echter merken dat het soms onvermijdelijk is dat de tabulair korund<\/a> verschijnen er zwarte of blauwe deeltjes. Wat is dan de reden voor de zwarte korund?
\nKorund in tabelvorm<\/a> is een kunstmatig slijpmiddel met een hoge taaiheid, dat goede economische effecten heeft bij gebruik voor zware slijpwerkzaamheden. Tabulair korund heeft een microkristallijne structuur van \u03b1-Al2O3, hoge taaiheid, het kan grote slijpdruk weerstaan zonder te breken en kan dikkere metaallagen snijden.<\/p>\n

1. De smelttijd is niet lang genoeg en er kan ook van worden uitgegaan dat het smeltproces onvolwassen is, wat resulteert in een lage zuiverheid van het korund zelf en een hoog gehalte aan onzuiverheden, en de kleur kan kleine zwarte vlekken vertonen;
\n2. Zwarte onzuiverheden, zoals de onzuiverheden die door het lichaam worden gedragen, worden niet gereinigd of opzettelijk gemengd en gewreven, waardoor het tabulair korund zwarte vlekken kan vertonen.
\n3. IJzerroest. Het plaatvormige korund zelf bevat ijzeroxide, dat verwijderd kan worden om het schoon te maken. Tijdens het productieproces kan de kleur van het plaatvormige korund onzuiver zijn door de toevallige vermenging met roest als gevolg van mechanische roest;
\nDe zuivere en onzuivere kleur van plaatkorund is een van de inspectienormen voor de kwaliteit van plaatkorund, en de kwaliteit van plaatkorund voldoet niet aan de norm, wat ook een grote invloed heeft op de functie van plaatkorund, zoals hardheid en slijpkracht. .
