Preparation of AlPO4-5 nano-pore crystals: Effect of alteration in precursor gel preparation on the morphology of crystals
Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

متن کاملGrowth and Morphology of Crystals*
This issue of “FORMA” presents an English translation of Haeckel’s book “Crystal Souls”, with Alan Mackay’s introduction and detailed annotations. The tanslation was accomplished by Alan, my respectable old friend since 1950’s. When this book published in 1917, Haeckel tried to attract people to beautifully organized variety of forms exhibited by radiolaria and snow crystals, and the close simi...
متن کاملDetermination of Crystal Growth Rate and Morphology of Barium Carbonate Crystals in a Semi-batch Crystallizer
A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. Results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3, the k...
متن کاملHopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
