Examples
Embodiment 1
[0022] a. Preparation of spinnable gel
[0023] After stirring and dispersing 1.2g of magnesium hydroxide in 50mL of deionized water, add 4.2g of citric acid, stir evenly, adjust to pH=5.0, and continue stirring overnight to obtain a transparent and stable solution. The solution is concentrated by rotary evaporation to obtain a transparent Spun gel.
[0024] b. Fiber preparation
[0025] After the above gel was made for 3 days, the filaments were picked with a glass rod to obtain gel filaments, dried in an oven at 100°C for 24 hours, and then calcined at 450°C to obtain magnesium oxide fibers.
Embodiment 2
[0027] a. Preparation of spinnable gel
[0028] After stirring and dispersing 1.2g of magnesium hydroxide in 80mL of ethanol aqueous solution, add 8.4g of citric acid, stir well, adjust to pH=4.0, and continue stirring overnight to obtain a transparent and stable solution. Concentrate the solution by rotary evaporation to obtain a transparent Spun gel.
[0029] b. Fiber preparation
[0030] After the above gel was left for 4 days, the filaments were picked with a glass rod to obtain gel filaments, dried in an oven at 100°C for 12 hours, and then calcined at 600°C to obtain magnesium oxide fibers.
Embodiment 3
[0032] a. Preparation of spinnable gel
[0033] After stirring and dispersing 2.4g of magnesium hydroxide in 120mL of acetone aqueous solution, add 8.4g of citric acid, stir evenly, adjust to pH=4.0, and continue stirring overnight to obtain a transparent and stable solution. Concentrate the solution by rotary evaporation to obtain a transparent Spinnable gel.
[0034] b. Fiber preparation
[0035] After the above gel was left for 7 days, the filaments were picked with a glass rod to obtain gel filaments, dried in an oven at 100°C for 8 hours, and then calcined at 600°C to obtain magnesium oxide fibers.
