The Creation

Fascination with petrified wood has stimulated interest in understanding the process of natural petrifaction. Early attempts of modeling natural petrifaction in the laboratory have been limited to mimicking incipient permineralization resulting in the creation of silica casts of pore spaces and inner cell walls. Silica lithomorphs produced through artificial silicification provided a possible avenue for studying microstructure of wood. More recently artificial petrifaction is motivated by the goal of creating advanced ceramic materials for engineering applications. The concept of using wood as a biotemplate has led to the creation of porous ceramics by cell wall replacement. To some extent artificial and natural petrifaction processes are comparable; although, some of the materials and procedures used in the laboratory are not found in nature. Research focused on the composition and structure of fossil wood from different-aged deposits is compared with research focused on the development of wood-templated porous ceramics. Differences and similarities in the pathways of natural silicification and creation of biomorphous ceramics are discussed. The comparison between artificial and natural silicification highlights the particular significance of the degree to which (de)lignification is needed for silica permeation.

Material Saving

Much industrial waste has mineralogical, chemical and physical characteristics similar to clays used in ceramic materials, enabling the reuse of these as raw materials in the ceramic industry. The ashes are a type of waste containing metals, which can cause air pollution, responsible for serious respiratory problems in the affected population. This study investigate the use of waste derived from the carbonization of a solid fuel (wood) in ceramic paste used for the manufacture of rustic floors, aiming its incorporation into the mix, partially replacing (lessening the environmental problem) the usage of raw material (saving clay), enabling the analysis of certain variables of sample preparation (characterization and formulation) and their influence on the final properties of the material. Results indicate that the partial replacement of clay by ash is feasible in the chemical and mineralogical aspects in the formulation of ceramic paste in the manufacturing of rustic floors.

The Creation

Abstract Polyvinyl chloride compositions are very popular in the cable industry. The range of domestic fireproof cable PVC plastics is limited to several manufactured brands that were developed more than 30 years ago and do not meet modern international standards. The creation of new environmentally friendly formulations of fireproof cable plastics with improved operational properties is an urgent task. This paper describes a method of synthesizing a novel ester compound of phenyl dixylenyl phosphate. The conditions for its production with maximum yield are selected. Physicochemical properties of the new flame retardant are studied. A non-toxic biodegradable PVC composition based on a plasticizer of dibutoxyethyl adipate and a novel flame retardant is formulated. The results of tests of the developed PVC-composite on the main indicators for cable products of the I40-13 brand are presented.
