CaO Sputtering Target Chemical formula : C a O Melting point : 2572 Density : 3.35 g/cm3 Notice : The chemical property is lively, can react with water, acid, have hydrogen generation.A layer of oxide and nitride films are formed on the surface of the air to prevent corrosion.When heated, almost all of the metal oxides are reduced.

Mesoporous calcium oxide–silica and magnesium …

Incorporation of basic metal species (oxides) such as magnesium oxide and calcium oxide into porous materials is a logical strategy for enlarging the uptake of acidic greenhouse gases such as CO 2. This work reports the development of ordered mesoporous silica (OMS) with incorporated magnesium and calcium oxides for CO 2 sorption at aient and elevated temperatures.

Metal Oxides, non metal oxides, K2O and Sulfur Oxide, …

16/8/2010· My problem in understanding is with metal oxides vs sulfur oxide. I figured that the metal oxide was basic but then I also thought the sulfur oxide would be basic, yet the sulfur oxide leads to creating both H2SO3 and H2SO4, which need to be neutralized by a base (which again was K2O, a metal …

Improvement of Mechanical Properties of Self Setting …

The aim of this study was to improve the mechanical performance of TTCP / DCPA cement by adding several metal oxides to tetracalcium phosphate during the fabriion process. Cements based on tetracalcium phosphate mixed with silica or titanium oxide showed significant increases in compressive strength, approximately 80 ‐ 100 MPa, whilst no change in the mechanical behavior of CPC was
