An active β-C_2S has been synthesized by a new technique, i.e., a mixture of CaO andaerosil with CaO/SiO_2 ratio equaled to 2 was first subjected to hydrothermal treatment atabout 100℃ and then ignition at a temperature not higher then 850℃ without adding stab-lizer. The mineral obtained was identified by XRD, IR and OM, and confirmed to be in β-form.The results of identification was comparable to those of C_2S synthesized by conven-tional method, i.e. heating the mixture at higher temperture (1340℃)....

An active β-C_2S has been synthesized by a new technique, i.e., a mixture of CaO andaerosil with CaO/SiO_2 ratio equaled to 2 was first subjected to hydrothermal treatment atabout 100℃ and then ignition at a temperature not higher then 850℃ without adding stab-lizer. The mineral obtained was identified by XRD, IR and OM, and confirmed to be in β-form.The results of identification was comparable to those of C_2S synthesized by conven-tional method, i.e. heating the mixture at higher temperture (1340℃). This β-C_2S obtained at lower temperature was very active. The harden paste showed asignificant strength at 3-days hydration.The compressive strength at 14-days hydration was10 times of that of the controlled β-C_2S.The contents of the combined water as well as theCa(OH)_2 released that determinated at various hydration periods showed once again thatthe hydration rate of β-C_2S obtained by the new technique is more rapid than the ordinaryβ-C_2S.

将CaO与气相沉积SiO_2按CaO/SiO_2=2的比例混合,混合料先经100℃常压水热处理,再在低于850℃下煅烧可制得C_2S,经X射线衍射、红外吸收光谱、反光显微镜观察均可证明它是β型硅酸二钙。同时用碳酸钙(C.P.)与气相沉积SiO_2按相同比例混合,用通常的方法在1340℃烧成的β-C_2S与之作对比试验。 采用此种新技术制得的β-C_2S水化活性是很高的。尽管它的浆体水/灰比值较高(0.55),但水化3d就具有一定的强度,水化14d的强度是普通β-C_2S同期令强度的10倍。由结合水量和水化释出的Ca(OH)_2量,均可证明它是一种活性很高的β-C_2S。

Porcelain-grade Kaolin is widely distributed in China, and has a long history of exploitation and utilization. It occurs mainly in Suzhou, Jiepai, Daton, Chaozhou, and Jingdezhen. Research on the porcelain Kaolin of China in the past years shows that most of the Kaolins in the North China are of sedimentary type, and that the ore deposits of Kaolin occur in the coal-bearing strata of Paleozoic and Mesozoic age. The origin of Kaolins in the South China is related to acid igneous rocks, such as granite etc, and most of them belong to weathering (residual) types, or to hydrothermal alteration types. The different geological conditions of ore-formation have resulted in a variation in mineral and chemical composition of the Kaolin, as woll as to difference in technological propcrties. The Chemical composition of Kaolin in Suzhou is close to the stoichiometrlc formula for standard Kaolinite. Its main mineral co mponents are Kaolinite, 7halloysite and 10halloysite. It has high plasticity and bonding proporties, and has high whiteness and refractoriness after burning. So it becomes an important raw material in the porcelain industry. The chemical composition of Kaolin in Jiopai is characterized by high SiO_2, low Al_2O_3 and Fe_2O_3, and little Na_2O and K_2O. It is mainly composed of poorly crystallized Kaolinite, 7 halloysite, muscovite, quartz and albite etc. It has a fine grain size and shows high whiteness and refractoriness after burning, and shrinkage is low. So it is a high-guality raw mateial preferred for the manufacture of fine porcelain table-wares. The chemical composition of Kaolin in Datong is similar to the composition of Suzhou kaolin. Its main mineral component is Kaolinite. Owing to the presence of an organic matter impurity. The Datong Kaolin has high plasticity and better shaping properties after ball-milling. The Kaolin in Feitienyan (Chaozhou) has high SiO_2, low Al_2O_3 and the K_2O is higher than in other Kaolin. Its principal minerals are illite and Kaolinite. It has moderate plasticity, and whiteness can rise to 70-80% reflectivity after burning. So it can be used directly in manufacturing porcelain. The chemical composition of Kaolin in Jingdezhen is characterized by high SiO_2 and Fe_2O_3, low Al_2O_3. After washing Al_2O_3 can increase to 34—36%. Its main minerals are Kaolinite and 7 halloysite.

我国制瓷高岭土分布广泛,开采历史悠久。其主要产区是江苏苏州、湖南界牌、山西大同、广东潮州和江西景德镇。近年来对制瓷高岭土的研究表明,我国北方所产高岭土多属沉积型,矿床赋存于古生代及中生代煤系地层内。南方所产高岭土在成因上则与花岗岩等酸性火成岩有关,多属风化残积型与热液蚀变型。各地高岭土由于成矿地质条件的差别,导致矿石的矿物、化学成分和工艺性能的差别。苏州高岭土的化学成分接近于标准高岭石的理论成分,它的主要矿物成分是高岭石、7多水高岭石和10多水高岭石,特高可塑性和结合性能,焙烧后白度高,耐火度亦高,所以它是制瓷工业重要原料。界牌高岭土的化学成分具征是SiO_2含量高,Al_2O_3、Fe_2O_3含量低,并含少量Na_2和K_2O,它主要由结晶差高岭石、7多水高岭石、白云母、石英和钠长石等组成,其工艺性能特征是细颗粒含量高、焙烧后白度高、耐火度高,但收缩小,因此是制造高档日用细瓷的优质原料。大同高岭土是一种硬质高岭土,其化学成分类似于苏州高岭土,主要矿物成分是高岭石,由于有机质的存在,球磨后具可塑性和成形性能。潮州飞天燕高岭土的化学成分特征是SiO_2高、Al_2O_3低,K_2O比一般高岭土高,它的主...
