- product A Another part of the spray powder (product A) was heated in an analogous manner to a calcination temperature of 200 ° C. and held at this temperature for 2 hours (product C). Parts of product C were each heated at a rate of 3 ° / min to a calcination temperature of 300 ° C (product D), 400 ° C (product E), 500 ° C (product F), 600 ° C (product G) and 700 ° C (product H) heated and held there for 2 hours each.
- the products A to H obtained were characterized by different methods (Table 1). In X-ray diffraction studies, all products (A - H) were clearly crystalline.
- the XRD diagram of the partzite shows a sequence of reflexes similar to that of the XRD diagram of the cubic Sb 6 O 13 (JCPCS file No. 33-0111).
- a measurement of the X-ray reflexes for the products A - F obtained at calcination temperatures of ⁇ 500 ° C led to the following values:
- the calcination products G and H which were obtained at temperatures of> 600 ° C, showed the XRD diagram 38-0453 and thus the tetragonal crystal structure of the anhydrous ZnSb 2 O 6 (Ordonezite). Furthermore, the specific BET surface area of the calcination products was determined (according to DIN 66 131 by gas adsorption (N 2 ) according to Brunner-Emmet-Teller). The products tempered at 150 to 400 ° C had the same BET surface area as the uncalcined spray powder (62 m 2 / g). As the calcination temperature increases, the specific BET surfaces decrease (see Table 1).
- the calcination products A to H were heated in a DTG-TG apparatus (Netzsch STA 429) with a heating rate of 5 ° C / min in air (flow rate 70 cm 3 air / min) from room temperature (25 ° C) to 1000 ° C , the sample lost weight with increasing temperature.
- Table 1 shows the "weight loss (DTG)" for the weight loss, which results from the difference between the initial weights of the samples in the DTG-TG apparatus and the weights of the samples at 1000 ° C. in the DTG TG apparatus result.
- the product obtained was pressure-filtered through depth filters.
