Problems solved by technology

[0006] (1) Only a single improvement measure, the effect is not obvious
[0007] (2) In terms of additive selection, the additive is relatively single and not the optimal additive, and the additive is too complicated, which will inevitably affect the low expansion of aluminum titanate
[0008] (3) The proportion of additives is not well controlled within the range that does not affect the excellent performance of aluminum titanate

Embodiment 1

[0024] (1) Prepare chemically pure TiO 2 and industrial pure Al 2 o 3 and oxide additives (Fe 2 o 3 , SiO 2 ) powder, wherein: the molar ratio of each raw material component is: TiO 2 :Al 2 o 3 : Fe 2 o 3 : SiO 2 =49:49:1:1.

[0025] (2) Wet mixing is adopted, that is, the weighed mixed powder is added to 10% PVA and wet mixed to form a muddy mixture.

[0026] (3) When the mixture obtained in (2) is dried to a humidity of 5%, use the molding method to make the above muddy mixture into a cylindrical compact with a diameter of 20 mm and a height of 25 mm, and then place the compact in a drying oven at 100 ° C. Incubate for 5 hours in medium temperature, and the heating rate from room temperature to 100°C is 50°C / h.

[0027] (4) Put the dry compact in (3) into a high-temperature resistance furnace, and set the temperature rise program: the temperature rise rate is 50°C / h from room temperature to 400°C, and the temperature rise rate is 200°C / h from 400°C to 1450°C. h,...

Abstract

A technology for producing an aluminium titanate material comprises the following steps that: (1) raw materials of TiO2 and Al2O3 and additives of Fe2O3 and SiO2 powders are prepared, and the molar ratio of all the components is that TiO2 to Al2O3 to Fe2O3 to SiO2 is (42.5-49.5%): (42.5-49.5%): (0.5-6%): (0.5-9%), and the molar ratio of TiO2 to Al2O3 is 1:1; (2) the weighed raw materials and additives are mixed with each other, 5-10% of polyvinyl alcohol is added into a mashed mixture; (3) the mixture of the step (2) is dried until the humidity is 3%-6%, a compression molding method is adopted to produce the mashed mixture into a cylindrical compression blank with the diameter of phi 20mm and the height of 5-30mm, and the compression blank is put in a drying oven of 100 DEG C to be thermally insulated for 4-6 hours or is dried for 24 hours in the room temperature environment; and (4) the compression blank of the step (3) is put in a high temperature resistance furnace to be heated to 400 DEG C and 1450 DEG C, so that the aluminium titanate material is synthesized.

Description

technical field [0001] The invention relates to a low thermal expansion, high temperature resistant aluminum titanate (Al 2 TiO 5 ) The preparation method of the material belongs to the field of material synthesis and processing ceramics. Background technique [0002] Aluminum titanate material is a new type of material integrating low expansion coefficient and high melting point. It is the best high temperature resistance among low expansion materials. In addition, it has low thermal conductivity, slag resistance, corrosion resistance and alkali resistance. And the non-wetting properties of various metals and glasses can be widely used in environments with harsh conditions such as thermal shock resistance, high temperature resistance, wear resistance, corrosion resistance, and alkali resistance, especially those requiring high thermal shock resistance. [0003] World Patent No. WO2005 / 018776 discloses a raw material mixture for sintering by adding 1 to 10 mass fractions o...
