Transmittance enhancement of La0.4Gd1.6Zr2O7 transparent ceramic by aqueous AM gel-casting with pretreated powder

Fabrication and phase transition of uranium‐doped LaxGd2−xZr2O7 transparent ceramics: A prospective neutron detection material

“…Then the powders were calcined at 1400°C for 8 h. In order to improve the performance of ceramic samples, twice ball milling was taken. Our former research [ 24 ] found that the grain size distribution of the pretreated powders prepared by ball milling twice is more uniform, and the grain size is smaller than that of the conventional powders fabricated by ball milling only once, which is beneficial to improve the optical uniformity of the ceramics and enhance the in‐line transmittance of ceramics. Thus, the powders were treated with a second ball mill.…”

Effect of CaO doping on densification and microstructure control of highly transparent La0.4Gd1.6Zr2O7 ceramics

“…But the transmittance is neither increasing in the visible region, nor the fabrication cost was economical. Later, in our previous works, the La 0.4 Gd 1.6 Zr 2 O 7 transparent ceramics are prepared through the aqueous acrylamide (AM) gel‐casting technique 17 . The transmittance achieved 78.7% at 1100 nm but the method is difficult to be applied in the facile solid‐state reactive sintering of La 0.4 Gd 1.6 Zr 2 O 7 ceramics, owing to the alkaline slurries caused by the hydrolysis of La 2 O 3 in the raw materials.…”
