Abstract: A method of additive manufacturing to form a component comprises successively depositing a plurality of layers to form the component. Depositing at least one of the plurality of layers includes depositing a layer of a first particulate precursor over a platen, depositing a second particulate precursor on portions of the platen over the layer of the first particulate precursor specified by a controller, and directing energy to the second particulate precursor deposited on the portion of the platen to cause an exothermic chemical reaction between the first particulate precursor and the second particulate precursor. The exothermic chemical reaction produces heat that sinters products of the chemical reaction to fabricate the layer of the component.

Abstract: The invention relates to the production of industrial ceramics and fire-resistant materials and can be used in the preparation of lightweight fire-resistant articles intended for use at temperatures of up to 1700 DEG C. The proposed charge for obtaining cordierite comprises the following components: 0.1-5.8 wt.% magnesium oxide, 0.3-14.8 % alumina, 49.4-53.4 % silica and 28.0-50.2 % alumino-magnesia spinel. The latter is obtained by one of two proposed methods from "fresh" saline or leached slags produced during the production of aluminium alloys. In one of the methods, alumino-magnesia spinel is obtained by roasting crushed slag containing 16-30 wt.% aluminium oxide, 2-15 % magnesium oxide, 30-70 % sodium and potassium chlorides, 2-15 % aluminium, 0.1-10 % silicon oxide, 2-8 % other additives; the roasting process involves heating the charge to 1450-1550 DEG C at a rate of 100-300 DEG C per hour and keeping it at the maximum temperature for between one and six hours. The second method involves the use of a leached slag comprising 20-50 wt.% alumium oxide, 3-20 % magnesium oxide, 5-25 % aluminium, 0.2-15 % silicon oxide and 5-20 % other additives. The slag is mixed with carbon powder (3-15 % by weight of the total mixture) and heated to 900-1200 DEG C until the initial mixture ignites. To increase the yield of alumino-magnesia spinel, the product can be subjected to further roasting at a temperature of 1400-1500 DEG C.
