Definitions

  • Silicon carbide with a grain size of 80/220 (mesh) in a proportion of 3.0-27.0% by weight is advantageous, silicon carbide with a grain size of 30/70 (mesh) in a proportion of 23.0-54 , 0 wt .-%, silicon carbide with a grain size of 16/24 (mesh) with a proportion of 7.0-25.0 wt .-% present, and preferably a maximum of 82 wt .-% SiC. But different grain sizes would also be suitable. The details are given in mesh.
  • a mix of powdery materials is preferably used, which is formed from an oxidically bound SiC mixture and an Al203 portion in the form of alumina and possibly also the addition of corundum and a powdery Si02 carrier or based on at least 90% SiO 2, preferably more than 95% SiO 2 with an average grain size preferably in the range of 40-150 ml, in particular 40-100 ml.
  • the residual content of the SiO 2 carrier is formed from conventional impurities, such as Fe203, A1203 and / or alkali or alkaline earth oxides and the like.
  • the proportion of SiO 2 carriers is preferably 5.0 to 15.0% by weight, preferably approximately 5.0 to 7.0% by weight. Unless otherwise stated, the percentages given herein relate to% by weight.
  • the silicon carbide is in powder form as an oxidically bonded SiC mixture, expediently with a grain size of SiC Mesh 80/220 in the range from 4 to 8%, SiC Mesh 30/70 in the range from 43 to 47% and SiC Mesh 16/24 in Range of 11 - 16%, with very fine powder with a size ⁇ 100mih up to 0.1%, in particular in the form of totanin powder.
  • Clay is in powder form, expediently in a grain size of 0-0.08 mm, whereby clay of various types is suitable, in particular clay of an average grain size of 3 ml to 5 ml is available.
  • Powdery, highly reactive clay is particularly suitable as the clay.
  • the silicon carbide is expediently present in an oxidically bonded SiC mixture, the following ranges being expedient, namely SiC Mesh 80/220 in the range from 3 to 6%, SiC Mesh 30/70 in the range from 23 to 29%, SiC Mesh 16 / 24 in the range of 7 - 11% and SiC fine grain ⁇ 100mih 0.5 - 2%, the percentages being given in percent by weight.
  • Suitable Si02 carriers are, in particular, materials available under the trade name Microsilica, in a suitable powder form.
  • the SiO 2 carrier is preferably added in the finest grain size, that is to say with a grain size preferably ⁇ 100 ml, in particular ⁇ 50 ml, expediently ⁇ 45 ml.
  • the Si02 carrier is preferably based on 90% Si02, the rest of the carrier component is quite desirable, such as usual impurities, such as oxides of iron, alkali and alkaline earth metal and the like.
  • the capsule or assembly material according to the invention avoids the disadvantages of the prior art by achieving a significantly higher strength and also increasing the resistance to temperature changes and reducing the risk of susceptibility to breakage.
  • the problem with conventional capsules has been that they often have to be replaced by new capsules due to contamination during the burning process of the cathode material, which causes a considerable amount of hazardous waste that can be eliminated through expensive recycling processes.
