Specimens were prepared by using iron-rich magnesia and high-pure magnesia as the main starting materials, and introducing fused corundum of 3%(in mass), 6%, 9%, 12%, 15% respectively and sintered at 1420°C.
However, there is no systematic study on in situ preparation of MgO-Al2O3-FeOn composite materials by using iron-rich magnesia and fused corundum.
In this paper, iron-rich magnesia is a source of iron oxides and spinel solid solution bonded periclase materials were synthesized in the reaction between iron-rich magnesia and fused corundum at high temperature.

In the experiments polypropylene, polycarbonate and ABS polymers were used as matrix materials.
The prepared materials were characterised by scanning electron microscopy.
We did not find any sign of agglomerates in the materials.
Polypropylene homopolymer, polycarbonate and ABS were used as matrix materials.
The structure of the multiwall carbon nanotubes in the matrix materials was studied by LP-FTIR and heating methods.

This preliminary work showed that hazelnut and peanut fillers could be utilized with proper additives in order to produce the composite materials with good physical and mechanical properties.
Although many studies were conducted on natural fiber reinforced composite materials, studies on waste natural fiber reinforced composites are limited.
Experimental Materials Hazelnut/peanut shell wastes, supplied from the industry, were used as the reinforcing / filling material.
Fabrication and reprocessing steps of composite materials Results and Discussions Effect of the reprocessing on the tensile properties The effect of the reprocessing on the tensile strength (TS) of LDPE and composite materials are exhibited in Fig. 2.

It has its applications in geosciences, biology, material science, biophysics, timber industry, construction industry, food industry, material science, industrial and agricultural in water distribution and etc.
“When the properties of a material are the same in all directions, the material is said to be isotropic.
Isotropic porous medium has received great attention during the last decades due to its applications in fibrous insulation materials in building engineering applications, geothermal, environmental engineering, tissue engineering, drug delivery, Nano porous materials etc.

Clay minerals are the main ingredients of the ocean floor sediments, which completely record a lot of geological information and have important meanings in the studies of source material, sedimentary environment, global climate change, sea-level fluctuation and ocean currents evolution.
Chen LR and Zhang XR(1986)[8] studied the gulf sediments and results showed that the northern gulf deposition is mainly from the river sediment and materials along the river flushing sediments.
