حضرت في هذا البحث عينتان من الأكسيد المشترك Al2O3/CdO بطريقة الترسيب المشترك باستخدام الأمونيا المركزة كعامل مرسب عند القيمة PH 8 من خلال مزج محاليل كلوريد الألمنيوم و كلوريد الكادميوم و كذلك مزج محاليل نترات الالمنيوم و نترات الكادميوم . درست خواص البنية النسيجية لهاتين العينتين و قورنت مع خواص البنية النسيجية للعينة المحضرة في بحث سابق عند الشروط نفسها. تؤثر طبيعة الأنيونات المستخدمة على نصف قطر المسام الوسطي أيضا، حيث يزداد عند الانتقال من الكبريتات إلى الكلوريد. و بينت النتائج ازدياد نسبة المسامية الدقيقة في الاتجاه نفسه.
Tow samples of Al2O3/CdO mixed oxide were prepared by co-precipitation method at PH 8 using concentrated ammonia as precipitated agent.The mixed system was prepared by mixing aluminum chloride solution with cadmium chloride solution and aluminum nitrate solution with cadmium nitrate solution which prepared in previous work. The nature of anions affected pore radii anions. The results showed the increasing of micro porosity.

Samples were prepared in different ways of Al2O3 / CdO and with one specific mole
Al / Cd: 1-0.25 mol, in the wet joint deposition method. - The thermal disintegration
of aluminum nitrate Al(NO3)3.9H2O and Cd(NO3)2.4H2O nitrate, and the reaction of
aluminum nitrate Al(NO3)3.9H2O and cadmium nitrate Cd(NO3)2.4H2O, with
NH4HCO3 with appropriate reactivity ratios, Sodium laureth sulfate (ALS), and the
effect of various methods of preparation on the properties of the textile structure of
the common oxide group Al O /CdO

It was found that the values of porous structure factors vary according to the
method of preparation, the two samples prepared in the manner of thermal
disintegration. The total pore size is slightly increased, while the mean pore radius
decreases from 2.71nm to 2.37nm, in contrast to the two hydrothermal heating
samples.
The total pore size increases significantly to 0.553ml /g. (SLS), a decrease in the
radius of the middle pores, and an increase in the value of the surface area.
In this work, six different samples of the Al2O3 / CdO system were prepared in a
co-precipitation method. Samples were prepared from saturated solutions for cadmium and
aluminum salts using concentrated ammonia as a precipitating agent at pH = 8 an
d after
settling and drying the sample was calcined at 400°C for two hours.
In order to studied the surface acidity by temperature programmed desorption (TPD)
method. The calcined sample was divided to two parts: The TG-DTA measurements was
carried on for the first part in order to determine the loss weight using thermal program in
the range 20-900°C and 10°C/min. The second part was impregnated in pyridine for 24h,
and dried at 120°C to remove the physical adsorbed pyridine and the TG-DTA
measurements were performed at the same conditions for the first part.
Differential curves were studied to calculate the weight loss produced by the
desorption of pyridine. The AC8 (1-1) showed the highest surface acidity value
(0.47m.mol / g), while the sample AC8 (1-0.25) gave the lowest acidity surface value
(0.11m.mol / g).
The effect of presence of gelatin, pectin and starch with 0.5% and
carrageenan 0.2% in the yogurt had been studied. Many tests techniques
as viscosity, penetration for yogurt gel, whey separation and sensory
evaluation had been established and com
pared.
Compacting hot mixes asphalt (HMA) at low temperatures or mixing it in the asphalt at high temperatures is a constant source of concern to researchers, as compacting and mixing at non-ideal temperatures leads to adverse results, which negatively affect the properties of asphalt concrete and lead to problems paving.
In this work composite hybrid materials were prepared from a base
material composed of epoxy and phenol - form aldehyde resins and
reinforced by 30% wt alumina and silica powders and asbestos
fibers. For samples were prepared with. Different ratio of
reinforcing material.
