In comparison with synthesis in air, the hydrothermal synthesis of La-CrO3 and LaCrO3 based materials has several advantages, such as the temperature of synthesis is 200-300℃ lower, the reaction process is simple, and the synthesized products are well crystallized with homogeneous grain size of 0.5-1μm. All the products prepared by both methods have the perovskite-type structure with monoclinic distortion (β=90.35-90.38°).It was found that the electrical conductivity of LaCrO3 is enhanced by...

In comparison with synthesis in air, the hydrothermal synthesis of La-CrO3 and LaCrO3 based materials has several advantages, such as the temperature of synthesis is 200-300℃ lower, the reaction process is simple, and the synthesized products are well crystallized with homogeneous grain size of 0.5-1μm. All the products prepared by both methods have the perovskite-type structure with monoclinic distortion (β=90.35-90.38°).It was found that the electrical conductivity of LaCrO3 is enhanced by doping with both Ca2+ and Mg2+, but the former is more significant. The(La1-xCax) CrO3 produced in oxidizing atmosphere appears as extrinsic conduction characteristics, whereas samples prepared in reducing atmosphere have intrinsic conduction characteristics. The intrinsic charge carriers result from the activation process of 2Cr3+ Cr4+ + Cr2+, and its activation energy is about 0.71eV. The(La1-xCax)CrO3 materials are an-tiferromagnets(Neel temperature about 288K) accompanying parasitic ferromagnetism.

水热法合成铬酸镧及铬酸镧基材料的温度较低(比空气中合成低200~300℃)、反应简单、产物均匀,粒度均一(0.5~1μm)。合成产物均具有单斜畸变(β=90.35~90.38°)的钙钛矿型结构。在LaCrO_3中掺杂Ca~(2+)置换部分La~(3f),对提高电导率的效果较掺杂Mg~(2+)者为优。氧化气氛下制得的(La_(1-x)Ca_x)CrO_3表现为非本征电导特征;还原气氛下制得者为本征电导。本征电荷载流子是由激活过程产生,其激活能约为O.7leV。(La_(1-x)Ca_x)CrO_3为反铁磁体(Néel温度约288K),兼具有寄生铁磁性。

A crystallization kinetic model for a spontaneous nucleation system of the M-Si- ZSM-5-type zeolites (M = B,Al,Ga,Ti, V,Cr or Fe) has been suggested on the basis of the investigation of the hydrothermal synthesis for this type of zeolites in tic. system of Na2O-HMDA-M2O3-SiO2-H2O at 150℃. The crystallization kinetic curves for the various M-Si-ZSM-5-type zeolites, obtained by calculation of the model, agree well with the experimental values.

在Na_2O-HMDA-M_2O_3-SiO_2-H_2O体系及150℃下通过对系列M-Si-ZSM-5型沸石合成及其晶化规律的研究(M=B,Al,Ga,Ti,V,Cr或Fe),提出了此类沸石的自发成核晶化动力学模型,各种M-Si-ZSM-5型沸石的理论晶化动力学曲线与实验点吻合较好。

The chemistry of hydrothermal synthesis of AlPO_4-5 molecular sieve from P_2O_5/Al_2O_3/(C_2H_4OH)_3 N system was investigated. Through the study on the physicochemical characteristics of this molecular sieve, it was found that it possessed good thermal stability, the temperature at which the crystal lattice collapse reached 50% was about 50℃ higher than that of REY, and the process of collapse was very slow.

The chemistry of hydrothermal synthesis of AlPO_4-5 molecular sieve from P_2O_5/Al_2O_3/(C_2H_4OH)_3 N system was investigated. Through the study on the physicochemical characteristics of this molecular sieve, it was found that it possessed good thermal stability, the temperature at which the crystal lattice collapse reached 50% was about 50℃ higher than that of REY, and the process of collapse was very slow. From the study on cracking activity of AlP0_4-5 molecular sieve, it was observed that in the pluse cracking reaction of pure hydrocarbon,AlP0_4-5 molecular sieve had a special selectivity for the olefin formation and there was a maximum value on the cracking activity vs temperature curve

本文叙述了P_2O_5/Al_2O_3/(C_2H_4OH)_3N体系水热晶化为AlPO_4-5分子筛的化学过程.通过对所合成的A1PO_4-5分子筛的物化性质的研究,发现该分子筛具有良好的热稳定性,其结构崩塌达50%时的温度比稀土Y型分子筛高50℃左右。同时,发现该分子筛结构崩塌是一缓慢过程.通过对AlPO_4-5分子筛裂化活性的考察,发现它在纯烃裂化脉冲反应中,对烯烃的生成有特殊的选择性;在裂化反应活性与反应温度的关系曲线中出现极大值。对以上特征进行了初步讨论。
