Technical Path:
The crystal structure of precision alumina ceramic materials should be alpha phase. Using a high-temperature furnace to transform the phase at low temperatures can suppress the growth of primary grains and improve the sintering activity of powder grains. The main focus is on controlling the phase transformation temperature and time. Using an X-ray diffractometer to detect the crystal structure of the powder, achieving the required phase transition rate and facilitating subsequent use.
