Abstract
Przedmiotem zgłoszenia jest kompozyt na osnowie tlenku glinu modyfikowany montmorylonitem w ilości od 0.1% wagowych do 30% wagowych. Zgłoszenie obejmuje też sposób wytwarzania modyfikowanego kompozytu na osnowie tlenku glinu, który polega na tym, że do pojemnika młynka wprowadza się proszek tlenku glinu oraz montmorylonitu gdzie udział masowy montmorylonitu zawiera się od 0.1% wagowych do 30% wagowych, poddanego wcześniej procesowi homogenizacji w ultradźwiękach przez 10 do 60 minut w 30 do 500 ml wody i/lub alkoholu izopropylowego na 1 gram montmorylonitu, całość poddaje się procesowi mieszania w wodzie i/lub alkoholu izopropylowym przez czas od 4 do 12 godzin a następnie mieszaninę suszy się w temperaturze 30°C do 100°C oraz przesiewa przez sito o wielkości oczek 0.1 - 0.5 µm, po czym prowadzi się proces konsolidacji przy użyciu technologii spiekania SPS w próżni w następujących parametrach: temperatura spiekania od 1100°C do 1500°C, prędkość grzania i chłodzenia z zakresu 1 - 300°C/min, czas wygrzewania od 1 do 30 minut, ciśnienie z zakresu 10 – 50 MPa.The subject of the application is an aluminum oxide-based composite modified with montmorillonite in amounts ranging from 0.1% by weight to 30% by weight. The application also includes a method for producing a modified composite based on aluminum oxide, which consists in introducing aluminum oxide and montmorillonite powder into the grinder container, where the mass fraction of montmorillonite ranges from 0.1% by weight to 30% by weight, previously subjected to the ultrasonic homogenization process by 10 to 60 minutes in 30 to 500 ml of water and/or isopropyl alcohol per 1 gram of montmorillonite, the whole thing is stirred in water and/or isopropyl alcohol for 4 to 12 hours and then the mixture is dried at 30°C to 100°C and sieved through a sieve with a mesh size of 0.1 - 0.5 µm, after which the consolidation process is carried out using SPS sintering technology in a vacuum with the following parameters: sintering temperature from 1100°C to 1500°C, heating and cooling speed in the range of 1 - 300°C/min, heating time from 1 to 30 minutes, pressure in the range of 10 - 50 MPa.
