Method for preparing nano anorthite porous heat insulation ceramic material by taking Al (OH) 3 as aluminum source
The invention relates to a nano anorthite porous heat insulation ceramic material, and belongs to the field of porous ceramics. The porous heat insulation ceramic material mainly takes quartz sand fine powder, nano CaCO3 and Al (OH) 3 as raw materials. The addition amount of the quartz sand fine powder is 30.0-38.0 wt.%, the addition amount of the nano CaCO3 is 25.0-35.0 wt.%, the addition amount of the Al (OH) 3 is 35.0-45.0 wt.%, the sum of the addition amount of the quartz sand fine powder, the addition amount of the nano CaCO3 and the addition amount of the Al (OH) 3 is 100 wt.%, and 20 wt.% of an ignition loss pore-forming agent is added. The nano anorthite porous heat insulation ceramic material is prepared by the following steps: proportioning, grinding, mixing, molding by vibration casting, drying and sintering at high temperature. The main phase of the porous heat insulation ceramic material is an anorthite phase; the main components of the glass are Al2O3, CaO and SiO2. The nano anorthite porous heat insulation ceramic takes Al (OH) 3 as an aluminum source, so that the cost can be effectively reduced, meanwhile, the nano anorthite porous heat insulation ceramic has excellent material compressive strength, low volume density and low heat conductivity, and a technical approach can be provided for low-cost preparation of an anorthite porous heat insulation ceramic material and energy conservation in a high-temperature kiln.
