查询词典 bulk density

The minerals of igneous formations were described and a bulk volume model based on mineral and including porosity was established. The logging response equations of density, apparent neutron porosity, acoustic travel time,gamma ray and volume photoelectric cross index were deduced. The volume content of four minerals in matrix was calculated. The igneous rocks were classified according to the international igneous classification scheme proposed by IUGS (International Union of Geological Society).

分析了火成岩中的矿物成分，并基于此建立了以矿物为基础并包含孔隙度的体积模型；建立了密度、视中子孔隙度、声波时差、伽马射线和体积光电吸收截面指数的测井响应方程，计算了岩石骨架中4种矿物的体积含量，依据国际地质科学联合会提出的火成岩矿物分类方案对火成岩进行了分类。

The result show that the samples are compactest when a-Al2O3/ content is 10wt% at 1450℃, zircon start to decomposes at 1350℃, little mullite are found at 1450℃, there are lots of mullite at 1500℃, apparent poroes become more, bulk density falls.

结果表明，1350℃时硅酸锆已经开始分解，添加a-Al2O3/为10%、温度为1450℃时烧结体最致密，相对密度达到95%，1450℃时已有少量莫来石相形成，1500℃时形成较多莫来石相，气孔增多，体积密度降低。

Results show that the mullite grogs can be gained by the method at 1700℃ as long as the control of the chemical composition of ingredients(content of Al2O3 and ratio of Al2O3/ SiO2 ,etc.) with apparent porosity＜2.5% and bulk density≥2.75g/cm3; the heating process can be divided three stages, which are formation of primary mullite, secondary mullitization stage and liquid phase sintering stage.Key words bauxite, coal gangue, mullite grogs

结果表明，只要控制好混合料的化学组成（Al2O3含量、Al2O3/SiO2比等），就可采用此工艺制备出莫来石料，其烧结温度为1700℃，所得莫来石料的显气孔率大于2.5%、体积密度大于或等于2.75g/cm3；加热过程可分为一次莫来石形成、二次莫来石化和液相烧结3个阶段。
