High oxidation resistance

Recently, a search has been conducted for solvents which are less hazardous to handle than halogen fluorides and hydrogen fluoride and which can be used to prepare solutions of the cationic species. Two have been found that are highly oxidation-resistant and suitable for this purpose 1,1,2-trichlorotrifluoroethane and... 

Also, the phenolic compounds in olives have a strong influence on the flavor of the oil and seem to be responsible for the high oxidation resistance of olive oil. The phenolic content in the flesh of olive fruits ranges between 1% and 3%, w/w, (66) oleuropein, vanillic, caffeic, p-coumaric acid, rutin, luteolin-7-glucoside, heterosidic ester of caffeic acid, and hydroxytyrosol (verbascoside) have been identified in olive fruits.

The combination of vinyl resins with epoxies is useful in formulations of solution coatings. Desirable characteristics are offered by low cost and high oxidation resistance of the vinyl resin. 

Monoliths made of metal foils can also be used as substrates in combustion catalysts [19, 20]. The metal is generally an iron- or nickel-based steel containing small amounts of aluminum. The aluminum diffuses to the surface on heating and oxidizes to form an adherent alumina layer. This alumina layer gives the alloy high oxidation resistance and is essentially self-healing as it arises from diffusion from the bulk material. It also provides good adhesion for the alumina washcoat. 

An SAE 15W-30, API CE/SG oil can be formulated with high oxidation resistance which meets API GL-4 by using ZDDP and sulphurised additives with some friction modiflers. The formulation is balanced between the lubricant requirements and the opposite requirements of the clutches and wet brakes.

Silicides represent the transition from intermetallics with predominantly metallic bonding to non-metallic compounds since silicon is no longer a metal, but a semiconductor. Nevertheless the silicides are often comprised within the intermetallics. Silicides were selected for high-temperature applications already in the past because of their potentially high oxidation resistance at highest temperatures [89-91]. Presently... 

Unlike most other aluminides which are considered for high temperature applications, NiAl with a B2 structure exhibits excellent oxidation resistance since a protective AI2O3 scale is readily formed during oxidation (Doychak et al., 1989 Nesbitt and Lowell, 1993). According to present knowledge, NiAl seems to be the only really oxidation resistant intermetallic, apart from some silicides (Meier et al., 1993). The physical reason for this high oxidation resistance is that the Al content... 

Metallic materials for be used as interconnects in SOFCs should fulfil a number of specific requirements [1, 2], Crucial properties of the materials are high oxidation resistance in both air and anode environment, low electrical resistance of the oxide scales formed on the alloy surface as well as good compatibility with the contact materials. Additionally, the value of the coefficient of thermal expansion (CTE) should match with those of the other cell components [3], These requirements can potentially be achieved with high chromium ferritic steels [4], however, previous studies [5] have shown that none of the commercially available ferritic steels seems to possess the suitable combination of properties required for long term reliable cell performance. 

MN-500 over conventional resins in the resistance to oxidation (Table 16.6). Whereas treatment of gel-type exchangers with oxidative solutions results in complete dissolution of resins in 3 days, MN-500 adds only 3% of moisture. The high selectivity of MN-500 with respect to trace metal cations in combination with its high oxidative resistance makes this commercial sulfonate very useful for condensate pohshing.

The polyimides have excellent chemical and radiation inertness and are not subject to UV degradation. High oxidative resistance is another important property. 

The studies on Hexanite-R ceramics based on the wurzite modification of boron nitride [164] demonstrated that the oxidation kinetic curves (Fig. 17) were very similar to that for B4C (Fig. 13). A rather high oxidation resistance is also exhibited... 

Whereas C o is readily reduced, it is difficult to oxidize. By using cyclic voltammetry (see Box 8.2) with ultra-dry solvent (CH2CI2) and a supporting electrolyte with a very high oxidation resistance and low nucleophilicity (["Bu4N][AsF6]), three...
