查询词典 gibbsite

At the same time, the SEM study shows that gibbsite occurs on the sample surface. At 200 ℃, as dawsonite sandstone is being dissolved authigenic siderite forms. At 300℃, chlorite deposit on parts of the sample surface. The weak solution of dawsonite sandstone at 100℃ and the formation of siderite at 200℃ illuminate that CO2 being in carbonates in the strata can not be released when CO2 phase is adding to the system.

同时，各温度下样品表面均有一水软铝石放射状集合体沉淀。200℃时，随着片钠铝石的溶解有自生菱铁矿生成，300℃时样品局部有绿泥石沉淀。100℃下片钠铝石的微弱溶解及200℃下菱铁矿的形成表明，在地层条件下以碳酸盐矿物形式捕获的CO2，不会由于CO2的二次注入而重新释放。

Acid is an excellent floater while gibbsite has no native floatabiligy at all.

School of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China）Abstract: Based on the theoretic calculation of crystal faces (001),(100),(010),(011),(110),(101) and (112) of gibbsite by CASTEP program, the relationship between unfold character of crystal face and chemical bond strength of surface of gibbsite was investigated.

摘 要：用剑桥连续总能量软件包程序，对氢氧化铝的各个经常显露面族的(001)、(100)、(010)、(011)、(110)、(101)和(112)面进行理论计算，分析氢氧化铝晶体的晶面显露特征与表面化学键力的关系。

It is found that from bond population calculation results, the bonding strength of Al—O bond of faces (011) and (011) of gibbsite are stronger than that of face (001). If the proportion of unfold of (001) surface is decreased and the proportion of unfold of (011) and (011) surfaces is increased to same possible extend, the bonding strength of Al—O bond of gibbsite would be more strong.

键布居分析结果表明，整体上氢氧化铝的(001)面的Al—O键的结合力不强，(011)和(110)面的Al—O键的平均键布居数较高，结合力较强；若小幅度降低(001)面的显露比例，并使(110)和(011)面较多显露，就有可能提高氢氧化铝表面的Al—O键的结合力。

The experimental results indicate that oleic acid has inhibitory effect on the precipitation, and the inhibitory effect is more obvious with increasing addition of oleic acid. Specially, oleic acid of 1×10^(-5) mol/L would facilitate the agglomeration of gibbsite, oleic acid of 1×10^(-4) mol/L would inhibit the agglomeration of gibbsite.

结果表明：油酸对铝酸钠溶液的种分过程产生比较明显的抑制作用，油酸的添加量越大，抑制作用越明显；添加1×10^(-5) mol/L油酸时可促进附聚，添加1×10^(-4) mol/L油酸时抑制附聚。

Both of the two karstic gibbsite bauxites are in Guangxi Province of the large-scalemineral deposits consisted of gibbsite and goethite.

广西2种岩溶型三水铝石铝土矿都是含三水锅石和针铁矿的大型矿床，但二者成矿过程通异。

Calculation results indicate that the total energy increases when oleic acid is on the surfaces of (001) and (100) of gibbsite respectively. This can explain that the stability of systems decrease when there is some oleic acid on the surface of gibbsite. The calculation results of equilibrium morphology and growth habit show that the volume of growth crystal is larger when some oleic acids with "horizontal" mode exist on the surfaces (001) and (100) of gibbsite.

计算结果表明：油酸接近氢氧化铝(001)和(100)表面时，体系总能量升高，说明油酸的存在可降低体系的稳定性；油酸在氢氧化铝(001)和(100)表面上时，油酸分子呈"卧"式时，长大后晶粒体积大于无杂质存在的情况，而油酸分子呈"立"式时，长大后体积小于无杂质时晶粒的体积。

School of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China）Abstract: By analyzing the crystal growth habit of gibbsite theoretically using Morphology program, the morphology character of crystal grain and the theoretic habit of gibbsite were studied.

摘 要：对氢氧化铝晶体生长习性进行Morphology理论研究，明确氢氧化铝晶粒长大后的晶粒形态特征及氢氧化铝的理论晶体生长习性。
