Definitions
- Catalytic coating agent process for its production and cooking, baking, roasting or grilling devices or parts obtainable with the coating agent.
- one of the subtasks of the invention is solved by a catalytic coating agent for surfaces of cooking, baking, roasting or grilling devices which contains oxides of at least one metal from the group cerium, sodium, potassium , Calcium, manganese, nickel and cobalt.
- a catalytic coating agent for surfaces of cooking, baking, roasting or grilling devices which contains highly porous silicates with at least one metal from the group cerium, sodium, potassium and calcium, and optionally one or more other silicates on ice.
- silicates can be inorganic compounds of silicon with aluminum and / or phosphorus, for example aluminum silicates, aluminum phosphates or silicon aluminum phosphates, such as SiAlPOs.
- a catalytic coating agent for surfaces of cooking, baking, roasting or grilling devices which contains highly porous aluminates with at least one metal from the group cerium, sodium, potassium and calcium or has several silicates.
- REPLACEMENT LEAF Surfaces of cooking, baking, roasting or grilling devices are provided, in addition to the highly porous silicates and at least one metal from the group cerium, sodium, potassium and calcium or the highly porous aluminates and at least one metal from the Group cerium, sodium, potassium and calcium
- the catalytic coating agents specified above can have an additional content of an alkali and / or alkaline earth metal compound with tantalum oxide, niobium oxide and / or tin dioxide.
- the compounds mentioned have high Coulomb field strengths between the cation and anion and strengthen the catalytic action in the areas close to the surface, these compounds being able to be sintered without decomposition with the enamel surface even at higher temperatures. Thereby, the surface area is increased, since the said compounds with the E-base substance form no chemical bonds with the Ver ⁇ 'temperatures employed.
- a catalytic coating agent for surfaces of cooking, baking, roasting or grilling devices which contains at least one boride, carbide, solicide and / or nitride of at least one metal the fourth, fifth and / or sixth subgroup of the periodic table.
- the catalytic coating agents according to the invention can be powders.
- a further sub-object of the invention is achieved by a process for the production of one of the catalytic coating compositions described above with a content of sodium, potassium, calcium, manganese, nickel and / or cobalt, in which the metals mentioned are dissolved in their aqueous solutions Salts
- the bare or enamelled surfaces are coated with a coating agent according to the invention (containing basic enamel powder) and the coating agent sinters or melts onto the surfaces or
- Another embodiment of the invention is finally directed to cooking, baking, roasting or grilling devices or their parts with surfaces which can be obtained by covering the base-enamelled surfaces with a coating agent containing at least one boride, Carbide, silicide and / or nitride of at least one metal from the fourth, fifth and / or sixth subgroup of the periodic table are coated and the coating agent is sintered on in air.
- a coating agent containing at least one boride, Carbide, silicide and / or nitride of at least one metal from the fourth, fifth and / or sixth subgroup of the periodic table are coated and the coating agent is sintered on in air.
- Target composition 65.3% CeO, 29.4% MnO,
- EH3 ⁇ TZELATT cooled, filtered off and dried at 120 and 250 ° C. and then slurried again with water, boiled, washed out, dried at 120 ° C. and annealed at 600 ° C. for 2 hours.
- Target composition 87% zeolite, 4.2% CeO
- zeolite 4A from Fluka
- 2.12 g of cerium, 6.23 g of manganese, 0.62 g of cobalt and 0.23 g of Nik ⁇ kei nitrate were suspended in 300 ml of water or ge solved and with 100 ml 3 percent. Hydrogen peroxide added. By dropping a concentrated one
- REPLACEMENT LEAF Ammonia solution was precipitated hot at a pH in the range of 8 to 9. After addition of 5 g of diammonium carbonate, the mixture was concentrated to 100 ml in the heat, filtered, dried at 150 ° C. and tempered at 500 ° C. for 2 hours.
- the catalytic properties of the product obtained can be found in Table 1.
- TGA Thermograviometric degradation rate
- Email II (50 wt.) 47.5 - 86.6
- Molybdenum disilicide with a grain size of less than 50 ⁇ m was sprayed onto an uncoated metal sheet in a plasma arc at a current of 600 A (53 V) with a spraying distance of 120 mm under an argon / hydrogen mixture (6: 1) within 1 min.
- the conveying rate was about 22 g / min and the molybdenum disilicide layer thickness was about 300 ⁇ m.
- a thermogravimetric breakdown rate of 45% was obtained after 1 h at 250 ° C. and 66% after 5 h.
