Conclusies
1. Toepassing van een keramiek-basismengsel welke vliegas en klei bevat, waarbij de gewichtsverhouding vliegas tot klei in het mengsel ten minste 70/30 is, voor de vervaardiging van keramische artikelen.
2. De toepassing volgens conclusie 1, waarbij de gewichtsverhouding vliegas tot klei in het mengsel in het bereik van 80/20 tot 95/5 ligt.
3. De toepassing volgens conclusie 1 of 2, waarbij de vliegas oplosbare zouten in het bereik van
0.5 tot 10 gew.% bevat.
4. De toepassing volgens één der conclusies 1 tot 3, waarbij de vliegas afkomstig is van biomassa.
5. De toepassing volgens één der conclusies 1 tot 4, waarbij de klei bentoniet is.
6. De toepassing volgens één der conclusies 1 tot 5, waarbij het keramiek-basismengsel voorts water en 0.01 tot 1 gew.% van een detergent, gebaseerd op het totaalgewicht water, bevat.
7. Werkwijze voor de vervaardiging van een keramische artikel, omvattende (a) het verschaffen van een keramiek-basismengsel zoals gedefinieerd in één der conclusies 1 tot 6; (b) het onderwerpen van het keramiek-basismengsel aan een vormstap; en (c) het bakken van het gevormde keramiek-basismengsel bij een temperatuur in het bereik van 800 tot 1300 °C, om het keramische artikel te verkrijgen.
8. De werkwijze volgens conclusie 7, waarbij het bakken wordt uitgevoerd bij een temperatuur in het bereik van 1000 tot 1250 °C.
9. De werkwijze volgens conclusie 7 of 8, waarbij de vormstap wordt uitgevoerd door gietvormen, droog-drukken of extrusie.
10. De werkwijze volgens één der conclusies 7 tot 9, waarbij het vliegas geïncubeerd wordt met water alvorens het te mengen met de andere ingrediënten om het keramiek-basismengsel van stap (a) te verkrijgen, en waarbij de werkwijze verder het drogen van het keramiek- basismengsel van stap (a) en het breken en/of malen van het gedroogde keramiek- basismengsel voorafgaand aan stap (b) omvat.
11. De werkwijze volgens conclusie 10, waarbij het watergehalte tijdens de incubatie in het bereik van 1 — 80 gew.%, gebaseerd op de hoeveelheid vliegas, ligt.
12. De werkwijze volgens conclusie 10 of 11, welke verder het toepassen van een glazuurlaag op ten minste een deel van het oppervlak van het keramische artikel verkregen in stap (c) omvat.
13. Keramische artikel verkrijgbaar door de werkwijze volgens één der conclusies 7 tot 13.
