Embodiment 1
[0035] Activated kaolin: use kaolin as raw material, raise the temperature up to 1000°C at a rate of 10°C / min, then increase to 1400°C at a rate of 5°C / min, keep warm for 2 hours and then cool naturally.
[0036] Take 10 g of activated kaolin as a benchmark, take 16 g of NaOH and 100 mL of distilled water; put the activated kaolin into a beaker equipped with NaOH solution, and stir with a glass rod; the beaker is sealed and placed on a magnetic heating stirrer to stir and heat up; When the temperature rises to 100°C, move the beaker to a water bath at 100°C for a constant temperature hydrothermal reaction; take out the beaker after 4 hours, fully wash the powder in the beaker until it is neutral, vacuum filter and store at 105°C Nano mullite powder can be obtained after complete drying.
Embodiment 2
[0038] Activated kaolin: use kaolin as raw material, raise the temperature up to 1000°C at a rate of 10°C / min, then increase to 1400°C at a rate of 5°C / min, keep warm for 2 hours and then cool naturally.
[0039]Taking 10 g of activated kaolin as a benchmark, take 12 g of NaOH and 100 mL of distilled water; put the activated kaolin into a beaker equipped with NaOH solution and stir with a glass rod; the beaker is sealed and placed on a magnetic heating stirrer to stir and heat up; When the temperature rises to 80°C, move the beaker to a water bath at 80°C for constant temperature hydrothermal reaction; take out the beaker after 5 hours, fully wash the powder in the beaker until it is neutral, vacuum filter and dry at 105°C Nano mullite powder can be obtained after complete drying.
Embodiment 3
[0041] Activated kaolin: use kaolin as raw material, raise the temperature up to 1000°C at a rate of 10°C / min, then increase to 1400°C at a rate of 5°C / min, keep warm for 2 hours and then cool naturally.
[0042] Take 10 g of activated kaolin as a benchmark, take 16 g of NaOH and 100 mL of distilled water; put the activated kaolin into a beaker equipped with NaOH solution, and stir with a glass rod; the beaker is sealed and placed on a magnetic heating stirrer to stir and heat up; When the temperature rises to 100°C, move the beaker to a water bath at 100°C for a constant temperature hydrothermal reaction; take out the beaker after 3 hours, fully wash the powder in the beaker until it is neutral, vacuum filter and dry at 105°C Nano mullite powder can be obtained after complete drying.
