Crystals of 1 asparagine and their structure

Article preview

For correct installation, 100 crystals were reviewed. The results of the revision and calculation of the probability of correct installation are given in the tables (see article). Using the example of asparagine, the legality of the decrease in the number of developed forms as the crystalline ball grows is extremely sharply and clearly demonstrated. In addition, during further crystallization, the appearance of any new forms that were not observed during the previous crystallization was never observed. From all the experiments described above, it clearly follows that the possibility of obtaining a much larger number of forms during the crystallization of a sphere, compared with what we observe during the free growth of crystals of the same compound.

Crystallization of some similar organic cobaltammines

Article preview

When crystallization is accelerated by cooling the initially heated solution, the crystals of these compounds begin to take on an increasingly needle-like appearance. The crystals of the iodide compound are so small (no more than 1/2 mm in length) that their goniometric study seems extremely difficult and I preferred not to do it, especially since this compound very easily decomposes in solution. Crystals of the chloride compound have already been described earlier. However, after the final clarification by E. S. Fedorov of the principles of correct installation, the symbols of the faces of these crystals should be changed according to the transition determinant (see article).

Copper sulfate crystals and their structure

Article preview

CuSO4 + 5H20 crystals have been studied by several authors. The most complete study of crystals of this compound was carried out relatively recently by Th. V. Barker in the laboratory of R. Groth. Copper sulfate crystals, as is known, belong to the cynacoidal class of the triclinic system. CuS04 + 5H20 crystallizes (at t° = - + 20°C) from an aqueous solution in very well-formed thick-table crystals. The article includes a diagram for the correct installation of crystals.

Determination of mesh densities of crystalline faces without constructions

Article preview

In his article “Image of the structure of a crystal with vectorial circles” Prof. E.S. Fedorov outlines a graphical method for finding the densities of meshes of crystal faces (more precisely: the squares of the densities of the corresponding meshes). Anyone who has dealt with determining the densities of meshes of faces using this method knows that in this case one should make some constructions, not particularly complex, but nevertheless quite time-consuming.This article aims to show how the task can be simplified by reducing drawing work to a minimum.

Crystals of one organic compound of cobalt

Article preview

Cobalt-diamine-dimethylglucimine chloride was obtained by L.A. Chugaev and presented by him to the Mineralogical Institute for crystallographic research (see article). Goniometric measurements (on a university, goniometer by E. S. Fedorov) and optical observations in polarized light revealed that the crystals belonged to the tetragonal system, the class of which could not be determined.

Calculation of spherical coordinates of faces after displacement

Article preview

Especially for triclinic crystals, when finding the faces of the vertical belt from tables of mesh densities, it is necessary to make a displacement of the defining faces, and such a displacement should be made with greater accuracy, compared with that which we can achieve graphically. In this case, it will be necessary to calculate the spherical coordinate ρ, which defines the faces after the disp;acement. Solving the question of such a calculation does not present any difficulty, and is already partly contained in one of the formulas given in the article by Sokolov and myself “Determination of the densities of networks of crystalline faces without the help of constructions".

Энигматические грани некоторых кристаллов

Article preview

При медленной кристаллизации кобальти-амин- хлоро - диметил - глюксимина при + 18 — 20° С, на некоторых кристаллах этого соединения появляются особые, загадочные грани. Эти грани отличаются прежде всего по своей величине, так как, обыкновенно, они больше других и образованы настолько совершенно, что при измерении можно поручиться за точность до нескольких секунд. Между тем, по своему положению они, по-видимому, не принадлежат к комплексу кристалла, так как символы их необыкновенно сложны, почти иррациональны.

Метод вычисления простейшего символа грани с определенной точностью

Article preview

Представим себе кристалл, измеряемый на универсальном, теодолитном гониометре. Положим, что нам приходится измерять грань, обладающую различными дефектами образования и дающую не один а несколько сигналов (благодаря развитию вициналоидов). При таких условиях точность измерения значительно понижается и в отсчетах углов φ (по вертикальному лимбу гониометра) и ρ (по горизонтальному лимбу) могут быть допущены довольно большие ошибки. Если даже грань образована достаточно хорошо, то все-таки часто можно поручиться за точность только в несколько минут, а большая точность достигается лишь в исключительных случаях.

О кристаллизации и некоторых физических свойствах кобальти-амин-хлоро-диметил-глиоксимина

Article preview

Кобальти-амин-хлоро-диметил-глиоксимин был впервые получен Л, А. Чугаевым, предложившим его одному из авторов для кристаллографического исследования. Кристаллизация производилась при температуре около + 20°С. из растворов в воде с 5% содержанием уксусной кислоты. В этом растворителе исследуемое соединение растворимо на холоде довольно трудно, причем растворимость его при нагревании повышается. Порошок вещества, взятый в избытке, нагре­вался в растворителе на водяной бане приблизительно до температуры кипения; затем горячий раствор отфильтровывался и охлаждался при комнатной температуре (около + 20° С). Результаты исследований см. в статье.

K2Cr2O7 crystals; their structure and twins

Article preview

Crystals of potassium dihydroxide were measured by Schabus (Wien. Ak. Veg. 1850) and he also stated a very perfect cleavage along {001} and less perfect along {100} and {010}. Potassium dichromate from aqueous solutions (t = + 20° C.) is released in well-formed crystals with growth planes {001} or {101}, which, as is known, belong to the pinacoidal class of triclinic system of cubic type.

Several experiments on crystals cut in the shape of spheres

Article preview

In brief reports of the 1st issue of volume I of the Mining Institute Notes” (p. 83), I reported on some experiments in the growth of spheres (hemispheres) prepared from crystals of chrome and potassium alum. Similar experiments were carried out with rock salt (NaCl) crystals from Stassfurt. A welded piece of such salt was turned into a hemisphere with a diameter of 10 m.m. with a central plane (100) and glued with wax onto a glass hemisphere of the same diameter.

On the growth of crystals cut into the shape of spheres

Article preview

When studying certain physical properties of crystals, it is often advantageous to operate with crystals turned into spheres, since in this case we directly obtain the specific magnitude of change for each vector. However, as far as I know, no experiments have ever been made on the crystallization of spheres artificially prepared from a crystal of a given solid substance. Meanwhile, this form of crystal is important in the sense of reducing the influence of crystal planes on the crystallization currents that arise during the deposition of a substance from a solution.
