摘要： A chemical oxygen generator includes multiple parallel sequentially connected chemical core sections that extend the duration of operation of the chemical oxygen generator. An end of a first core section is contiguous with a chemical core high reactivity section, and a thermal insulation layer is disposed between an end of a second core section and the chemical core ignition plate, as well as between the bodies of the first and second core sections. A chemical core transition section is disposed between the other end of the first core section and the second core section, to insure that the reaction front propagates properly.

摘要： Provided is an oxygen generating composition comprising a metal powder fuel, a transition metal oxide catalyst, a reaction moderator, a binder, an additive, and an oxygen source. The additives are feldspar or anhydrous aluminum silicate, or both. The oxygen generating composition can be used to generate oxygen on thermal decomposition. The oxygen generating composition is suitable for incorporation into oxygen generating candles. Oxygen generating candles of the present invention have the advantages of lower chlorine concentration, better reaction rate control, and lesser sensitivity to temperature effects on oxygen generation when compared with conventional oxygen generating candles. Additionally, oxygen generating candles comprising the compositions of the present invention can result in candles that do not contain barium compounds, and are non-hazardous, stable to moisture, CO2, and to air, and are suitable for either wet or dry processing methods.

摘要： The oxygen generating compositions contain carbon-free metal powder as fuel to minimize generation of carbon monoxide. The carbon-free metal powder can be selected from copper, zinc, and antimony, and mixtures thereof, and can be used in combination with tin or iron.

The oxygen generating compositions can optionally include a binder. An oxygen generating candle can also have an ignition pellet having a composition of about 25-50% by weight copper, zinc or antimony, 5-20% by weight Co.sub.3 O.sub.4, about 2-5% by weight glass powder, 0-25% by weight KClO.sub.4, and the balance being substantially NaClO.sub.3.
