矾土

Thermometric titrimetry has had a long association with the production of alumina from bauxite; where it has traditionally been applied to the determination of the caustic and aluminate contents of recirculating "Bayer Process" liquors.

温度滴定测量长期以来都和从矾土中提炼生产氧化铝有关系–传统上被用来测定再循环拜尔法液体中的苛性碱和铝酸盐的含量。

Typically, these membranes are made from porous carbon, zirconium oxide, or alumina, although a wide range of materials are being tested.

虽然大量的材料尚处于试验阶段，但通常典型膜可由多孔碳材，氧化锆和矾土制成。

Using special alumine grog as aggregate and powder,adding active SiO2 fine powder and α-Al2O3 fine powder,using pure calcium aluminate cement as bonding agent,and adding effective additives,the prepared mixture was shaped by casting vibration,then a kind of lower cement and high alumina casting preformed block was made.

以特级矾土熟料为骨料和粉料，配以活性SiO2微粉和α－Al2O3微粉，以纯铝酸钙水泥作结合剂，并加入有效的外加剂制成混合料，经浇注振动成型，得到一种低水泥高铝质浇注料预制块。

They then left the transformation to complete itself, and it would nottake less than ten or twelve days for the sulphuret of iron to be changedto sulphate of iron and the alumina into sulphate of alumina, two equallysoluble substances, the others, flint, burnt coal, and cinders, not beingso.

硫化铁变成硫酸铁和矾土变成硫酸铝的过程至少需要十天到十二天，他们经过上述的安排以后，就让它自己去变化，不再照料了。硫酸铁和硫酸铝都能在水中溶解，可是其他如火石、焦炭、灰渣等是不能在水中溶解的。

Used to produce alumina cement, abrasive materials, ceramic industry, as well as a variety of aluminum compounds.

Bauxite based mullite was prepared with grade Ⅱ broken bauxite (3 mm) and broken coal gangue(3 mm) as starting material according to formula w(Al2O3)=68%~72% in bauxite based mullite grogs.

以Ⅱ等高铝矾土碎矿(≤3 mm)和煤矸石碎矿(≤3 mm)为原料，按照矾土基莫来石熟料w(Al2O3)=68%~72%的要求，将它们按一定比例混合配制成混合料，接着将混合料湿磨至0.044 mm以均化化学成分，经湿法挤泥成型、烘干后分别在1 550℃、1 600℃和1 700℃煅烧6 h，冷却后测定其显气孔率和体积密度以确定烧结温度。
