Petrified wood stone or wood.
Technology is in the process of development!
Artificially created petrified wood in water does not sink, does not burn in the fire, does not rot, is not exposed to atmospheric precipitation. The material repels water. Has excellent sound and thermal insulation properties, resistance to temperature and strength characteristics.
Petrified wood, stone wood, fossil. The process of formation and production properties:
Stone tree, petrified wood, fossil wood is trees, which grew in past geological epochs, replaced by different minerals: silica (quartz), basalt or granite.
A significant accumulation of wood fossils in a small area called the petrified forest.
Previously, under natural conditions, the processes of fossilization (the petrification of a tree, from GK. πέτρος — stone) flowed century and Millennium. They took place underground, when wood was buried under sediment. Under the action of water in the absence of oxygen in the wood had been a breakdown of organic substances like cellulose and lignin, which were replaced by mineral rocks, bring water. In the end, the tree gradually turned to stone, preserving their original microscopic structure, including rings.
At present, scientists were able to speed up these natural processes and to develop the technology of petrification of wood.
For this purpose the wood is placed in an aqueous solution of basalt and special chemical additives. Due to matched mode (high temperature and pressure) of crushed basalt penetrates wood, replacing cellulose and lignin. The process of petrification of wood occurs during the day.
As a result of processing the wood retains its appearance, but acquires new properties. Externally this stone, the wood looks almost as usual.
Artificially created petrified wood in water does not sink, does not burn in the fire, does not rot, is not exposed to atmospheric precipitation. The material repels water.
In fact, the stone wood is a new environmentally friendly building material with excellent acoustic and thermal insulation properties, resistance to fire and to temperature and strength characteristics.
The new material can be used in low-rise construction, and also as a heat insulator.
Scientists continue experiments with different species of wood.
