“…The densification occurs mainly during the reaction process and sintering process, that is to say, the sintering processing is shown from 700°C to 1600°C. YAG is produced from 700°C to 1000°C [5][6]. The reaction temperature is lower than the 1100°C for synthesizing YAG powders from Al 2 O 3 -Y 2 O 3 composite powders, because ZrB 2 particles are changed electrically during the entire sintering process, which produces a plasma among ZrB 2 particles to purify the nearby particle surfaces and increase the sintering activity.…”

ZrB 2 , YAG and Al 2 O 3 are widely applied because of some excellent performances, but ZrB 2 is easily oxidized in the high-temperature air. To keep advantages and improve disadvantages of ZrB 2 , the shell-core structure A1 2 O 3 -Y 2 O 3 /ZrB 2 composite powders are prepared by the co-precipitation methods, the high density ZrB 2 -YAG-Al 2 O 3 ceramics is prepared by the spark plasma sintering (SPS). The mechanical properties of prepared ceramics under the 20MPa sintering pressure and 4min holding time are shown, which indicates the mechanical properties are increased with increasing sintering temperature, and the increasing ratio of mechanical properties is faster at sintering temperature from 1300℃ to 1700℃. When the sintering condition is 1700℃, 20 MPa and 4 minutes, the Young's modulus and the fracture toughness are 421.8 GPa and 12.23 MPam1/2, respectively. The reinforced phase (YAG-Al 2 O 3 ) is coated on the surface of ZrB 2 crystal, that is to say, the YAG-Al 2 O 3 is show on the crystal boundary, which is help for the densification and the mechanical properties.

“…YAG is also very stable in a high-temperature oxidizing atmosphere and remains unchanged for 100 hours without any change in weight. Therefore, YAG is also considered one of the candidate materials for high-temperature structural materials [5][6][7][8].…”

The composite ZrB2 powder coated A12O3-Y2O3 prepared by co-precipitation method were densified via the spark plasma sintering (SPS) and then researched the oxidation resistance at high temperature. ZrB2 powder must have the better dispersibility during the coating processing for obtaining the better coating effect. Effect of dispersant on the dispersibility of ZrB2 powder in the liquid is researched in this paper, the results show ZrB2 powder have the better dispersibility as the dispersant for PMAA and the content for 2vol%, which lay foundation for synthsising the better coating effect coated A12O3-Y2O3-ZrB2 composite powder.

Zirconium diboride (ZrB2) ceramics with high melting point, high hardness, good electrical and thermal conductivity, good neutron control and other characteristics, can be widely used in high-temperature structural ceramics, composite materials, electrode materials. In order to improve ZrB2 difficult densification and high-temperature oxidation, the properties of coated Al (OH)3-Y(OH)3/ZrB2 composite powders prepared by co-precipitation method were investigated in this paper, The conclusions are shown that the effect of coated composite powders is getting worse with the accelerated titration rates. the coating effect will be worse with the increasing reaction time. When the concentration of mixed solution is lower, the coated effect is better. When the synthesis condition is that the titration rate of 10ml/min, and the reaction time was 1h, mixed solution ion concentration of Y3+=0.119mol/L and Al3+=0.231mol/L, the coated effect of composite powders is better.
