Plate zeolite and as a separate mineral is referred to the 7th structural group of geilandite containing stebite too; through according to zone crystalline properties it is close to the mordenite structure; clinopzeolite appears to be isostructure of the gitlandite.
Clinopzeolite characteristic feature is its monowedge singony with the following parameters of the lattice (elementary) cell

Zeolites are aluminosilicates containing oxides of alkali, alkaline-earth metals, which are strictly differed by regular pore structures being filled by water under usual thermal temperature conditions.
General chemical formula of zeolites is the following: Me2/nO. Al2O3 – xSiO2 – yH2O (where M is the cation of the metal integrity, N is its valency.

Quite a new technology of asphalt concrete is proposed. Actually, the technology is in the substitution f bitumen for a new adhesion of a road-way covering.
The composition consists of a 2 components:
- crushed stone wastes,
- adhesion “Haralex”.
There are 5 – 6 components in existing concrete asphalt.
There are certificates of authorship in Armenia and Italy.
For the implementation of the given technology on industrialized level it is necessary to have a new type of asphalt laying machine. The company “Wirtgen” is engaged in designing of similar machines.

The group of specialists has developed the method of obtaining artificial stone-shaped materials on the base of widespread perlite sand in Armenia. Perlite resources are estimated for more than 10 mln cube meters in the Republic. The elaborated technology is free of wastes and ecologically pure. Numerous laboratory specimens were obtained, which by their mechanical, physical and chemical properties considerably exceed such natural stones, as granite, marble or onyx. There is an opportunity to get a wide range of colors for the materials by addition of a small amount of cheap pigments to the initial mixture.

The elaboration regards the area of metallurgy for rare metals.
Armenia is rich with copper and molybdenum raw during treatment of which copper and molybdenum concretes are obtained. Except basic metals (copper and molybdenum) they contain a great amount of rare and noble metals (selenium, rhenium, tellurium, gold, and silver).
For metallurgic treatment of molybdenum concentrates selenium and rhenium are converted into roaster these gases in water towers selenium and rhenium are changed into acid washing solutions.

The elaboration refers to the new method of the charge preparation for ferromolybdenum melting. The usual charge includes technical trioxide of molybdenum cinder obtained during the burning of molybdenum concentrates. Common technical trioxide is characterized by higher content of harmful impurities – sulphur and non-ferrous metals. While using usual burnt molybdenum concentrates for ferromolybdenum melting the last has a low graded as there is an exceeding content of sulphur and non-ferrous metals in it.

Armenian Republic is rich in resources of colored minerals in accordance of which natural pigments have been obtained.
Important colors are violet, dark red, lilac, brown, red, lemon, ochre, green and their tints.
They are characterized by cheapness, simplicity in comparison with artificial (synthetic) pigments, by wide range of colors of the painting compounds, high color fastness, compliance with known adhesions, fire-and explosion-proof; non-cancerageneous, non-toxically, non-radioactivity, low content of heavy metals, sanitary demands.
