Alumina-keramiek is wyd gebruikte keramiek. As gevolg van sy superieure prestasie word dit in die moderne samelewing wyd gebruik om aan die behoeftes van daaglikse gebruik en spesiale prestasies te voldoen.<\/p>\n

1. Die hardheid is bepaal deur die Shanghai Silikaatnavorsingsinstituut van die Chinese Akademie vir Wetenskappe, en die Rockwell-hardheid was HRA80-90, wat slegs tweede was n\u00e1 diamant en die slytasiebestandheid van slytasiebestand staal en vlekvrye staal ver te bowe gegaan het.<\/p>\n

2. Die slytasiebestandheid van alumina-keramiek is uitstekend. Die slytasiebestandheid is 266 keer ho\u00ebr as di\u00e9 van mangaanstaal en 171,5 keer ho\u00ebr as di\u00e9 van ho\u00ebchroomgietyster, soos gemeet deur die Powder Metallurgy Research Institute van Central South University. Volgens ons kli\u00ebntetrackingopname oor meer as tien jaar kan die dienslewe van die toerusting onder dieselfde werksomstandighede ten minste tien keer verleng word.<\/p>\n

3. Liggewig, met 'n digtheid van 3,5 g\/cm\u00b3, slegs die helfte van di\u00e9 van staal, wat die toerustinglading aansienlik kan verminder.<\/p>\n

Algemene vormmetodes kan vir alumina-produkte gebruik word, soos die dro\u00eb persmetode, die injeksie-metode, die gietmetode, die ekstrusie-metode, die filmbindingsmetode, ensovoorts. In die afgelope jare is filterpersvorming, direkte verhardingsvorming, gelinspuitvorming, sentrifugale injeksie-vorming en vryvorming van soliede voorwerpe in China en in die buiteland ontwikkel. Verskillende alumina-produkte met verskillende vorms, groottes, komplekse vorms en presisie vereis verskillende vormmetodes.<\/p>\n

Die mikrostruktuur van alumina-keramiek bepaal dat dit 'n reeks voordele moet h\u00ea, soos: Alumina-keramiese materiale het die kenmerke van uitstekende isolasie, lae ho\u00ebfrekwensieverlies en goeie ho\u00ebfrekwensie-isolasie. Alumina-keramiek is onbrandbaar, roesvry, solied en nie maklik om te beskadig nie, en het uitstekende eienskappe wat ander organiese en metaalmateriale nie kan gelykstel nie.Die slytasiebestandheid van alumina-keramiek is dieselfde as di\u00e9 van korund en bereik 'n Mohs-hardheidsgraad van 9. Die slytasiebestandheid is vergelykbaar met di\u00e9 van 'n superhardlegering. Die hittebestandheid van alumina-keramiek word gekenmerk deur 'n klein termiese uitbreidingsko\u00ebffisi\u00ebnt, ho\u00eb meganiese sterkte en goeie hittegeleiding. Alumina-keramiek het die eienskappe van chemiese korrosiebestandheid en weerstand teen gesmelte metaal.<\/p>\n
