-The NFR category 2.A.6 (other) is not comparable with the CRF structure. So the CRF category 2.A.4.a Ceramics production includes the same figures. Information about the key source relevance can be found in [[sector:ippu:mineral_industry:start|2.A - Mineral Industry]].+

 The ceramics industry in Germany is very heterogeneous. It involves a large number of products that are characterized by different fields of application and corresponding chemical compositions. In addition to clay (as the main raw material), sand and other natural raw material amounts, synthetically produced materials such as aluminium oxide and silicon dioxide are also used. The mixture, which is homogenously mixed from primary raw materials and only in small quantities of secondary raw materials, is burned mainly in tunnel kilns and hearth furnaces at kiln temperatures between 1,100 - 1,300°C.  The ceramics industry in Germany is very heterogeneous.

-For submission in 2018, the production figures (activity rates) were evaluated as completely as possible by the Federal Statistical Office. In order to complete the data available, the annual production of each product category was determined in the context of an expert study in cooperation with the Federal Statistical Office (J. Gottwald et al., 2017) [(J. Gottwald et al., 2017: Prüfung der Vollständigkeit der Berichterstattungskategorie 'Keramische Erzeugnisse' insbesondere feinkeramische Erzeugnisse, Dessau-Roßlau, 2017; https://www.umweltbundesamt.de/sites/default/files/medien/1968/publikationen/2017-01-19_dokumentationen_01-2017_emissionsrelevanz-feinkeramikbranche.pdf | Document (PDF) )]. Data from the Federal Statistical Office are available in different units (tonnes, square metres, pieces, value) depending on the product. In order to ensure consistent processing of the data, it is necessary to standardize the dimensions in tonnes by using conversion factors. +For submission in 2018, the production figures (activity rates) were evaluated as completely as possible by the Federal Statistical Office.

 The conversion factors for facing bricks, backing bricks and roof tiles are calculated differently. On information provided by the Bundesverband der Deutschen Ziegelindustrie e. V. this calculation in respect of technical discussions were fundamentally revised. Up to now, for the conversion of the volume data of the official statistics for the whole time series an average value for the gross density from 1994 is used. Now new average values for the bulk density of backing bricks for the year 2016 (BV Ziegel, 2019). The bulk density has increased over time since 1994 has fallen steadily, which is due to the increase in the proportion of well-insulating lightweight bricks. The Values for raw densities for the years between 1994 and 2016 were interpolated linearly. The brick product group has by far the largest share in the ceramic Total production. A review of the methodology for the other sectors of ceramic industry was not necessary. The conversion factors for facing bricks, backing bricks and roof tiles are calculated differently.
