Claim Text:
1. A method of controlling a chemical reaction in a fluidized bed reactor chamber for silicon production with a gas, comprising: providing the gas at a first temperature in a gas inlet area, wherein the first temperature is between 200° C. to 400° C.; heating the reaction chamber to a second temperature, wherein the second temperature is between 600° C. to 800° C.; inhibiting heat of the reaction chamber from reaching the gas inlet area using a first side of a distribution plate wherein the first side comprises a first material having a first thermal conductivity; and transporting the gas from the gas inlet area through holes stretching between the first side and a second side in the distribution plate to the reaction chamber while cooling the holes using a base structure of the distribution plate, wherein the base structure is of a second material having a second thermal conductivity and also surrounds the holes, wherein the second material has a higher thermal conductivity than the first material, wherein transporting the gas from the gas inlet area through the holes in the distribution plate to the reaction chamber further comprises transporting the gas through holes comprising at least one wall at least partly made of a third material having a third thermal conductivity higher than the first thermal conductivity of the first material, wherein the second material is in thermal contact with the third material, and wherein the second material is different from the third material.
