It relates to infrared radiators.

ェライト系セラミックスが一般に用いられている。(Prior art) Far-infrared radiators include alumina, silica, zircon,
Ceramics such as β-subodumene or cordierite are used, but among these, alumina and silica have a large coefficient of thermal expansion, and crystal phase transitions occur during heating and cooling, resulting in poor thermal shock resistance. It was inferior. Furthermore, in order to sinter zircon densely, it must be fired at a temperature of 1,400°C or higher, and if clay is added to increase its plasticity,
Excess silica in this clay turned into cristobalite, which inhibited thermal shock resistance. Therefore, lithium-based ceramics or cordierite-based ceramics are generally used as far-infrared radiators.

製造するのは不都合な点が多かった。(Problem to be Solved by the Invention) However, the sintering range of these lithium ceramics or cordierite ceramics is limited to a certain temperature range, and it is difficult to sinter them densely, making it difficult to industrially manufacture them. There were many inconveniences.

The present invention has been completed based on this finding.

転炉スラブを使う。In the present invention, lithium ceramics include petalite, spodumene, and eucryptite ceramics. In addition, in the present invention, the lithium-based or copierite-based ceramic is one that is formed by blending raw materials and reacting during firing to become a lithium-based or cordierite-based ceramic, or is already a lithium-based or cordierite-based ceramic. The powder that has become a ceramic is used as a raw material. In addition, Kibushi clay and Frogme clay are used as clay, and blast furnace slag from blast furnace or mine slag is used as clay.
Use converter slab.

Below I, the fire resistance is low and the moldability is poor. Further, if slag is added in an amount of 30% by weight or more, the refractoriness will be lowered, and if it is added in an amount of 1% by weight or less, the radiation characteristics will not improve.

In addition, Ca is contained in the slag.
It contains a large amount of O, and this CaO plays the role of a mineralizer, and by adding appropriate amounts of clay and slag, the sintering temperature can be adjusted automatically.
