Abstract

The solution of the problem of amber (succinite) flaw detection by microscopic analysis and luminescent analysis of amber macrostructure is proposed. The proposed method allows to obtain a rapid analysis of the defective state of the material structure. Given the growing demand for the use of such materials on an industrial scale and the insufficiency of existing methods, the proposed method may be a new solution to the problem of flaw detection. The basis of the proposed method for studying the macro structure of amber is transmission spectroscopy, luminescent analysis method. Samples of raw, heat-treated and pressed amber of the Palmniken Deposit obtained in the city of Kaliningrad of the Russian Federation were used as objects of research. Samples of different degrees of transparency and heat treatment were selected. It is established that the distinctive luminescence intensity at the defect boundaries is a characteristic of the presence of internal defects of the material and indicates the location of internal fractures, microcracks and other mechanical damage. The proposed method may be of interest in the theory of knowledge of materials science, research related to the processes of flaw detection of organic materials.

Highlights

Amber is a unique material of fossil resin, which is more than 30-90 million years old
Amber deposits are found all over the world and the most famous deposits are from the basins of the Baltic sea, the Dominican Republic, Sicily, Borneo, Spain, etc [1]
Heat-treated and pressed amber from the Palmniken Deposit in Kaliningrad of the Russian Federation were selected as the material basis of the experimental study

Summary

Introduction

Amber is a unique material of fossil resin, which is more than 30-90 million years old. Amber is valued in many fields of science and technology due to its unique physical and chemical properties, and in the arts and crafts-for its color, beauty and has been used as a precious stone since ancient times. More than a hundred deposits of fossil amber-like resins, as well as similar modern formations, about 90 % of all world reserves of which are located in the field of the Kaliningrad region [2]. The initial composition, conditions, Deposit, time of origin of amber-like resins affect the physical, chemical, mechanical properties and acquire distinctive direct and indirect signs-attributes that allow to make the most complete and informative systematization or classification [6]
