Abstract
The X-ray diffraction technique is one of the techniques that are widely and precisely used in determining the structural properties of materials through which materials can be developed and their areas of use increased, and Cork is considered one of the polymers of very low industrial value and is used only for secondary purposes such as packaging, and it is possible to have any other uses of high value by doping the cork with materials that can change its physical properties. Therefore, this study aimed to improve the structural properties of cork (polystyrene) doped by aluminum oxide with doping ratios (0.1,….., 0.9) molar, through X-ray diffraction, where the results showed that all the prepared samples are multi-crystallized of the types (cubic, mono, triple and hexagonal). And it was found that the preferred direction of growth is the level (211), and the crystal size of all the prepared samples was calculated, and it was found that it increases with the increase in the percentage of doping. Also, the density and number of crystals were calculated as each of them decreases with the increase of the doping percentage. This study concluded that cork, through its structural properties and after doping by aluminum oxide, can be of great technological benefit by having properties that are very similar to those of a semiconductor.

The cork tree has a remarkable capacity to create suberose tissue from its inner bark
Cork is one of the oldest substances known to mankind, a material that is based like a sponge and its origin is plant and is lightweight, and a insulating material worse against water, sound, heat and electricity, it does not absorb water and it is characteristic of cork that it bears high pressure, and this substance appeared in the centuries BC where the barges were made of them, as well as to float fishing nets being a light material floating on the sea surface, and used as pipe plugs [2,3,4]
Cork plugs have been made since the 17th century
Summary
The cork tree has a remarkable capacity to create suberose tissue from its inner bark. Cork is one of the oldest substances known to mankind, a material that is based like a sponge and its origin is plant and is lightweight, and a insulating material worse against water, sound, heat and electricity, it does not absorb water and it is characteristic of cork that it bears high pressure, and this substance appeared in the centuries BC where the barges were made of them, as well as to float fishing nets being a light material floating on the sea surface, and used as pipe plugs [2,3,4]. The cork is produced after obtaining the outer shell of the cork tree as it contains an outer layer of coarse sand which is brown, and is adjacent to the cork material and attached to the so-called tannic acid, the first step begins with
