Method for producing a domestic appliance plate and domestic appliance device having a domestic appliance plate
View Patent ↗A method for producing a domestic appliance plate from a starting mixture. In order to provide a domestic appliance plate having a high resistance to thermal shock, good thermal insulation, and advantageous mechanical properties, at least magnesium silicate hydrate, kaolinite, calcined kaolinite, and aluminum oxide are used for the starting mixture.
1. A method for producing a domestic appliance plate comprising:
a) providing a starting mixture of components comprising magnesium silicate hydrate, kaolinite, calcined kaolinite, and pure aluminum oxide;
b) forming a green sheet from the starting mixture; and
c) sintering the green sheet at an elevated temperature such that at least two of the components are joined together by heat.
2. The method of claim 1 , further comprising adding ball clay to the starting mixture to increase plasticity.
3. The method of claim 1 , further comprising adding high-purity synthetic cordierite to the starting mixture.
4. The method of claim 1 , further comprising adding to the starting mixture at least one member selected from the group consisting of fireclay cordierite, aluminum titanate, and coloring agents.
5. The method of claim 1 , wherein prior to step b), kneading the starting mixture into a homogeneous paste.
6. The method of claim 5 , wherein step b) comprises extruding the homogeneous paste into the green sheet.
7. The method of claim 1 , wherein the elevated temperature ranges from 1200° C. to 1400° C.
8. The method of claim 1 , wherein the components are present in an amount of at least 50 wt. % based on the total weight of the starting mixture.
9. The method of claim 5 , wherein the components are present in an amount of at least 50 wt. % based on the total weight of the homogenous paste.
10. A method for producing a domestic appliance plate comprising:
providing a starting mixture of components comprising magnesium silicate hydrate, kaolinite, calcined kaolinite, pure aluminum oxide, and cordierite;
sintering the mixture of components at a sintering temperature that is above the melt temperature of the cordierite.
11. The method of claim 10 , wherein the starting mixture is a homogenous paste.
12. The method of claim 11 , wherein the components are present in an amount of at least 50 wt. % based on the total weight of the homogenous paste.
13. The method of claim 10 , wherein the sintering temperature ranges from about 1200° C. to 1400° C.
