| 简介 |
The present invention relates to a ceramic composition for a lampshade, the ceramic composition including, based on total weight thereof : 50-80 parts by weight of clay, red clay, kaolinite, elvan, feldspar, silica, pottery stone, quartz, boulder or a mixture thereof; 10-30 parts by weight of alumina, bentonite, iron oxide, silicon oxide or a mixture thereof; 7-15 parts by weight of gypsum, ash or a mixture thereof; 3-10 parts by weight of a fiber made of a short fiber, a long fiber, a filament, a whiskers, a tow, a fabric, a mat, a felt, or at least one mixture selected therefrom; and 3-5 parts by weight of cerium oxide, zirconium oxide, or a rare earth metal oxide which is a mixture thereof, wherein the composition further includes 3-20 parts by weight of calcium aluminate as a binder, based on total weight of the ceramic composition, and 1-10 parts by weight of a mixture of an anion emitting material and a far infrared radiating material at a weight ratio of 1 : 1, based on total weight of the ceramic composition, wherein the anion emitting material is selected from the group consisting of strontium, vanadium, zirconium, cerium, neodymium, lanthanum, barium, rubidium, cesium or gallium, and the far infrared radiating material selected from the group consisting of quartz, monzonite, gneisses or rhyolitic tuff. According to the present invention, the ceramic composition for a lampshade stably maintains its size constantly even when fired at high temperature for manufacturing a lampshade, and far infrared ray beneficial to the human body may be radiated by using heat generated from a lamp.COPYRIGHT KIPO 2015 |
