Examples
Embodiment 1
[0041] Weighed 1.1476g of sodium carbonate solid and 1.4389g of crown material waste. After X-ray fluorescence (XRD) analysis of the crown material waste, it was found that the zirconia content was 92.53%. After mixing, they were placed in a ball mill for ball milling. The rotational speed of the ball mill was 500 rpm. The ball milling time is 2h. The resulting powder is then calcined in a muffle furnace. The calcination procedure in the muffle furnace is to raise the temperature from 20°C to 850°C, and calcine at a constant temperature of 850°C for 6h. The product can be obtained.
Embodiment 2
[0043] Weigh 1.3779g of sodium carbonate solid and 1.4389g of dental crown material waste. After X-ray fluorescence (XRF) analysis of the dental crown material waste, it can be known that the zirconia content is 92.53%, and they are mixed and placed in a ball mill for ball milling . The rotational speed of the ball mill was 550 rpm. The ball milling time is 1.5h. The resulting powder is then calcined in a muffle furnace. The calcination temperature in the muffle furnace was 800°C, and the calcination was carried out at a constant temperature of 800°C for 5h. The product can be obtained.
Embodiment 3
[0045] Weighed 1.1476g of sodium carbonate powder and 1.4389g of crown material waste. After X-ray fluorescence (XRF) analysis of the crown material waste, it was found that the zirconia content was 92.53%, and then the obtained powder was calcined. The calcination temperature is 750°C, and the calcination is carried out at a constant temperature of 750°C for 8 hours. The product can be obtained.
