Ultrahigh-temperature far-infrared catalytic radiation ring

Abstract

The invention discloses an ultrahigh-temperature far-infrared catalytic radiation ring which is prepared from the following raw materials in percentage by weight: 3-8% of lanthanide-series rare earth, 10-20% of Si3N4, 10-20% of BN, 30-50% of ZrO2, 3-8% of Y2O5, 3-8% of CeO2, 15-25% of aerodux and 3-8% of sea bittern. The ultrahigh-temperature far-infrared catalytic radiation ring can bear high temperature, and has enough far-infrared radiation rate.

Description

technical field [0001] The invention relates to a radiation ring, in particular to an ultra-high temperature far-infrared catalytic radiation ring. Background technique [0002] There are three forms of heat conduction: convection, conduction, and radiation. Only under radiation conditions, its heat conduction speed is the fastest, reaching the speed of light of 300,000 km / s, and it does not require a medium. However, it needs to be selected under the condition of up to 2500 ℃, and meet the conditions of use in the occasion of combustion, which has a large thermal shock change, and there is no similar product at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultra-high temperature far-infrared catalytic radiation ring, which not only withstands high temperature, but also has a sufficiently high far-infrared radiation rate. [0004] The present invention solves the above-mentioned technical problem...
