A pair of reference electrodes and a flame rod are placed in contact with charged particles in a flame produced by a burner. When a voltage is applied between the flame rod and the burner by a power source, a current (I.sub.fr) flows between them due to the flame conductivity. A potential difference (V.sub.12) between the pair of reference electrodes is detected by a potential difference detector. The dynamic flame impedance between the pair of reference electrodes is defined as the slope of the I.sub.fr -V.sub.12 relationship and is independent of I.sub.fr.

This invention provides a catalytic composite for decomposing fats and oils, and a heating cooker having the catalytic composite mounted therein. The catalytic composite comprises a porous sheet made of ceramic fibers and/or metal fibers, and a catalyst. The catalytic composite is capable of decomposing oil grease or stains deposited on the inner wall of a heating cooker and cooking exhausts emitted in the process of cooking by oxidation, at relatively low temperatures.

Catalytic composite and a cooker having the same

A mixed oxide comprising oxides of Ce, Cu and Mn wherein an atomic ratio of Ce to a total atom number of Cu and Mn is from 1:2 to 2:1 and the metals are present in the mixed oxide in the oxide forms of CeO.sub.2 and Cu.sub.x Mn.sub.3-x O.sub.4 wherein x is a number larger than 0 (zero) and less than 3, which can catalyze the oxidation of organic materials.

Mixed oxide catalyst and coating or porous material comprising the same

An IR radiation heating element comprising a substrate and a coating film formed thereon from a coating composition for IR radiation heating which comprises an oxide of a transition metal or a mixed oxide of transition metals, ZrO.sub.2 and polyborosiloxane, which element has improved IR radiation efficiency when heated.
