2With mass fraction: 60%, 37%, 1%, 2% mixes, with material: ball: water=wet-milling in 1: 2: 18 hours, mist projection granulating, powder is old, dry-pressing formed diameter 120mm, the thickness 10mm base substrate made, 100-150 ℃ of oven dry 3-5 hour, the base substrate after the oven dry at 1350 ± 10 ℃ of heat preservation sintering 2-4 hours, is made circular far infrared ceramic plate.Adopt with embodiment 1 same procedure and make the same recipe nano far infrared ceramic powder.Preparation far infrared ceramics glaze water, its compound method is: conventional ceramic base glaze (dry weight) mass fraction is 90%, and the nano far infrared ceramic powder mass fraction is 10%, mixes obtaining far infrared ceramics glaze water in 3 hours through ball milling.Adopt the glaze spraying method to execute far infrared ceramics glaze on ceramic kettle body inwall, through 130 ℃ of oven dry 4 hours, 1250 ℃ made far-infrared ceramic kettle body in glaze firing 7-9 hour.Be assembled into the far-infrared ceramic electric kettle by accompanying drawing 1.Use this far-infrared ceramic electric kettle (1200W) to boil 1.2 liters of running water, boiling in 3 minutes 100% compares energy-conservation 25% with the running water that boils with power stainless steel electric kettle with amount.
Far-infrared ceramic heating plate of the present invention is to adopt with MgO, Al
2O
3, SiO
2, β-spodumene is that primary raw material mixes TiO simultaneously
2, CeO
2, produce the far-infrared composite ceramics heating plate that a kind of low-expansion high-radiation is penetrated rate.Owing in this composite ceramics, adopt MgO, Al
2O
3, SiO
2Synthetic α-Jin Qingshi (2MgO2Al
2O
3SiO
2), its crystal structure is an orthorhombic system, is the silicate of circulus, structure is not tight, easily introduces doped chemical (as Ti
4+, Zn
4+, Zr
4+Deng) cause distortion of lattice, thus the symmetry when reducing the ion vibration improves far infrared transmissivity; Introduce rare earth oxide simultaneously (as CeO
2, La
