The study main researched the effect of apparent porosity of porcelain architectural ceramic materials on the far-infrared radiance property. T3J1, a formula of Mg-K-Al-Si system was used for the research and the materials were obtained when the body was sintered under five temperature spots in the sintering range. The material’s water absorption, apparent porosity and the far-infrared emissivity were measured and the results showed that the apparent porosity is increased because of the low sintering temperature. The more apparent porosity cause the surface of the material more coarse and the more radiation source and higher far-infrared emissivity. A correlation curve formula refers to the effect of the change of the apparent porosity (Δρ) of the T3J1 on the far-infrared emissivity(ε) was got under the mathematical analysis, that is: ε=εmax-0.0017-0.0004eΔρ/0.13138 |
