When further cooled, the airborne water vapor will condense to formliquid water (dew). When air cools to its dew point through contact with a surface that is colder than theair, water will condense on the surface.[1][2] When the temperature is below the freezing point of water,the dew point is called the frost point, as frost is formed rather than dew.[3] The measurement of thedew point is related to humidity. A higher dew point means there will be more moisture in the air.[2]DEWPOINT\HUMIDITY CONVERSION FORMULAS????\▲ Introduction Why humidity measurements Humidity ▲ Humidity Measurements for Tungsten Powder Production Hard-Metallurgy at Ceratizit Laboratory furnace Humidity measurements ▲ XDEM predictions© CERATIZIT \ 17.01.20197 CONTENT\ HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\ HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\© CERATIZIT \ 17.01.201910 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTIONSinter-HIP furnacesVacuum sinter furnaces\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE11Container with powderH2 H2OWO2(OH)2(g) HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\© CERATIZIT \ 17.01.201912 HUMIDITY MEASUREMENTS\© CERATIZIT \ 17.01.201913 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTIONRaw Data\© CERATIZIT \ 17.01.201914 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTIONReproducibility !\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE15 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\© CERATIZIT \ 17.01.201916 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTIONPressure [mbar]Temperature [°C]\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE17 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE18 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE19 HUMIDITY MEASUREMENTS FOR TUNGSTEN POWDER PRODUCTION\▲ Introduction Why humidity measurements Humidity ▲ Humidity Measurements for Tungsten Powder Production Hard-Metallurgy at Ceratizit Laboratory furnace Humidity measurements ▲ XDEM predictions© CERATIZIT \ 17.01.201920 CONTENT\© CERATIZIT \ 17.01.2019 FUßZEILE \ FOOTNOTE \ PIED DE PAGE21 XDEM PREDICTIONS??\THANK YOU!A.A.
