SPINEL POWDER AND MANUFACTURING PROCESS THEREFOR, AND PROCESSES FOR PRODUCING THERMAL SPRAYING FILM AND GAS SENSOR ELEMENTS |
摘要 |
Disclosed is a spinel powder obtained by mixing a magnesia raw-material with an electrically fused alumina, followed by firing of the mixture. The particles of the spinel powder are coated with granular spinel particles.. Therefore, there are provided a spinel powder and a simple method for producing the same, which is superior in thermal spraying property and has a unique particle shape. In particular, there is provided a method for producing a spinel powder which contributes to a reduction in the variation of characteristics of sensors, for example, as a thermal spraying powder for forming a protective coating of a gas sensor element. |
