Luxovit is calcined flint, i.e. flint that has been calcined, or heated to high temperatures. The raw flint contains about 0.2 % of chemically bound water. When the flint is calcined to about 1200°C the water is liberated and the stone becomes white and crystalline in character. This crystalline structure of the stone is what gives it its extremely high reflectivity of light and heat. After calcination the white flint is crushed and sieved into the required fractions.
The different Luxovit fractions are suitable for use in a number of areas and the sheet below shows the most typical segments.
|0.0-2.0 mm coarse grained||X|
|0.0-2.0 mm fine grained||X|
