[0026] The present invention provides a preparation method of lanthanum aluminate green ceramics described in the above technical solution, comprising the following steps:
[0027] Aluminum hydroxide, lanthanum oxide, nickel oxide, chromium oxide and titanium oxide are mixed and wet ground to obtain a slurry; the amount of aluminum hydroxide, lanthanum oxide, nickel oxide, chromium oxide and titanium oxide meets the requirements of the above technical scheme LaAl 11-2X- Y Cr Y Ni X Ti X o 18 stoichiometric ratio;
[0028] Drying and calcining the slurry in sequence to obtain a powder material;
[0029] Pressing the powder material to obtain a ceramic green body;
[0030] The ceramic body is sintered to obtain lanthanum aluminate green ceramics.
[0031] The preparation method provided by the invention is environmentally friendly, pollution-free, less energy consumption, low cost price, short production cycle, simple and controllable, and good repeatability.

Embodiment 1
[0044] Preparation chemical composition is LaAl 11-2X-Y Cr Y Ni X Ti X o 18 Lanthanum aluminate green ceramics, where X = 1.5, Y = 0.2. Accurately weigh aluminum hydroxide, lanthanum oxide, nickel oxide, chromium oxide and titanium oxide according to the stoichiometric ratio of the above-mentioned X and Y;
[0045] Move the weighed solid raw material into a ball milling tank, pour in absolute ethanol three times the mass of the solid raw material, place the ball milling tank in a star-shaped ball mill, and add oxidized powder with a particle size of 5mm and 10mm according to a ball-to-material ratio of 2:1. Zirconium balls were ball milled for 24 hours at a speed of 4800r / min to obtain a slurry;
[0046] Pour the slurry into a beaker, place it in an oven at a temperature of 80°C to dry, put the dried powder into a box-type electronic furnace, and calcinate it at 600°C for 4 hours to obtain a powder material;
[0047] The powder material is ground and sieved, and pressed ...
Embodiment 2
[0050] Preparation chemical composition is LaAl 11-2X-Y Cr Y Ni X Ti X o 18 Lanthanum aluminate green ceramics, where X=2.0, Y=0.3. Accurately weigh aluminum hydroxide, lanthanum oxide, nickel oxide, chromium oxide and titanium oxide according to the stoichiometric ratio of the above-mentioned X and Y;
[0051] Move the weighed solid raw material into a ball milling tank, pour in absolute ethanol three times the mass of the solid raw material, place the ball milling tank in a star-shaped ball mill, and add oxidizing powder with a particle size of 5 mm and 10 mm according to a ball-to-material ratio of 3:1. Zirconium balls were ball milled for 48 hours at a speed of 4800r / min to obtain a slurry;
[0052] Pour the slurry into a beaker, place it in an oven with a temperature of 80°C to dry, put the dried powder into a box-type electronic furnace, and calcinate it at 700°C for 6 hours to obtain a powder material;
[0053] The powder material is ground and sieved, and pressed...
