LIGHTWEIGHT KILN FURNITURE
To provide a kiln furniture having reduced bulk density, also having excellent corrosion resistance and thermal shock resistance and suitable as a use when powder raw material is subjected to firing treatment.SOLUTION: A kiln furniture is used when powder raw material comprising a lithium-containing compound, a cobalt-containing compound, a manganese-containing compound, a nickel-containing compound or an iron-containing compound is subjected to firing treatment, and comprises inorganic powder having corrosion resistance and heat-resistant inorganic fiber as the main components to the lithium-containing compound, the cobalt-containing compound, the manganese-containing compound, the nickel-containing compound and the iron-containing compound, has a prescribed mineral composition, has a bulk density of 0.7 to 1.5 and has a hot linear expansion coefficient of 5×10-6/K or lower at RT to 700°C.SELECTED DRAWING: None
【課題】 粉末原料の焼成処理時の用途として好適な、かさ密度が小さく且つ耐食性及び耐熱衝撃性に優れた窯道具を提供する。【解決手段】 リチウム含有化合物、コバルト含有化合物、マンガン含有化合物、ニッケル含有化合物、又は鉄含有化合物からなる粉末原料の焼成処理時に用いる軽量窯道具あって、前記リチウム含有化合物、コバルト含有化合物、マンガン含有化合物、ニッケル含有化合物、及び鉄含有化合物に対して耐食性を有する無機粉末と、耐熱性無機繊維とを主たる構成要素とし、所定の鉱物組成を有し、かさ比重が０.７〜１.５であり、ＲＴ〜７００℃における熱間線膨張係数が５×１０−６／Ｋ以下である。【選択図】 なし
