鋁礬土又稱礬土或鋁土礦，主要成分是氧化鋁，系含有雜質(zhì)的水合氧化鋁，是一種土狀礦物，白色或灰白色，因含鐵而呈褐黃或淺紅色。密度2.4-2.5g/cm3，硬度1～3，不透明，質(zhì)脆，極難熔化，不溶于水，能溶于****溶液，主要用于煉鋁，制耐火材料。 

      熟料為灰白淺黃及深灰色，它主要用于高鋁質(zhì)耐火材料，也可用來制作電熔棕剛玉。高鋁礬土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+MgO、K2O+Na2O等雜質(zhì)含量和熟料體積密度與吸水等項指標(biāo)來分級的。

      輕燒鋁礬土，又稱輕燒粉，是凈水劑聚合氯化鋁的原材料，是鋁礬土經(jīng)過加工生產(chǎn)出來的礦粉材料，主要成分是氧化鋁，系含有雜質(zhì)的水合氧化鋁，是一種土狀礦物。白色或灰白色，因含鐵而呈褐黃或淺紅色。密度3.9～4g/cm3，硬度1～3，不透明，質(zhì)脆。極難熔化。不溶于水，能溶于****溶液。

      (1)生礬土，即礬土原礦石(天然沉積巖類)。

      (2)熟礬土，將生礬土經(jīng)高溫煅燒后(1200～1700℃)稱為熟礬土。

      高鋁礬土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+ MgO、K2O+Na2O等雜質(zhì)含量和熟料體積密度與吸水等項指標(biāo)來分級的。

      1、煉鋁工業(yè)。用于國防、航空、汽車、電器、化工、日常生活用品等。  

      2、精密鑄造。礬土熟料加工成細(xì)粉做成鑄模后精鑄。用于軍工、航天、通訊、儀表、機(jī)械及醫(yī)療器械部門。 

      3、用于耐火制品。高鋁礬土熟料耐火度高達(dá)1780℃，化學(xué)穩(wěn)定性強(qiáng)、物理性能良好。 

      4、硅酸鋁耐火纖維。具有重量輕，耐高溫，熱穩(wěn)定性好，導(dǎo)熱率低，熱容小和耐機(jī)械震動等優(yōu)點(diǎn)。用于鋼鐵、有色冶金、電子、石油、化工、宇航、原子能、國防等多種工業(yè)。它是把高鋁熟料放進(jìn)融化溫度約為2000～2200℃的高溫電弧爐中，經(jīng)高溫熔化、高壓高速空氣或蒸汽噴吹、冷卻**成了潔白的“棉花”——硅酸鋁耐火纖維。它可壓成纖維毯、板或織成布代替冶煉、化工、玻璃等工業(yè)高溫窯爐內(nèi)襯的耐火磚。消防人員可用耐火纖維布做成衣服。 

      5、以鎂砂和礬土熟料為原料，加入適當(dāng)結(jié)合劑，用于澆注盛鋼桶整體桶襯效果甚佳。 

      6、制造礬土水泥，研磨材料，陶瓷工業(yè)以及化學(xué)工業(yè)可制鋁的各種化合物。

Bauxite also known as alumina and bauxite, main component is aluminum oxide, hydrated alumina containing impurities, is a kind of earthy mineral, white or grey, due to iron is brown yellow or light red. Density 2.4-2.5g/cm3, hardness of 3 ~ 1, opaque, brittle, very difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution, mainly used in aluminum, refractory materials.
1, aluminum smelting industry. Used in national defense, aviation, automotive, electrical, chemical, daily necessities, etc..
2, precision casting. Bauxite is processed into fine powder and made into mold. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sector.
3, used for refractory products. High bauxite clinker high refractoriness of up to 1780 DEG C, strong chemical stability, good physical properties.
4, aluminum silicate refractory fiber. Has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, has the advantages of small heat capacity and resistance to mechanical vibration etc.. For steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. It is the high alumina clinker into the melting temperature of about 2000 ~ 2200 degrees of high temperature in the electric arc furnace, the high temperature melting, high pressure air or steam injection, cooling, became a white "cotton" - aluminum silicate refractory fiber. It can be pressed into a fiber blanket, plate or woven into cloth instead of smelting, chemical, glass and other industrial furnace lining refractory brick. Fire fighters can be made of refractory fiber cloth clothes.
In 5, magnesia and bauxite as raw material, adding appropriate binder, used for pouring ladle lining the whole barrel effect.
6, made of alumina cement, abrasive materials, ceramic industry and chemical industry can be a variety of aluminum compounds.
