Abstract

The invention discloses a processing method of bone ashes. The method is characterized by comprising the following steps of: mixing the bone ashes with silicon nitride powder or silicon powder, a sintering aid and reinforcing and toughening additives to form a main bone ash ingredient, molding the main bone ash ingredient to obtain a green body, and sintering the green body to obtain a product, wherein the main bone ash ingredient comprises the following components according to weight percentage: 0.1%-40% of bone ashes, 55%-99.9% of silicon powder or silicon nitride powder, 0-25% of sintering aid and 0-40% of reinforcing and toughening additives. The new method disclosed by the invention is used for storing and utilizing the bone ashes. The product obtained by the method disclosed by the invention has the advantages of high rupture strength, good machining property, stable chemical property, good thermal shock resistance, good wear-resisting property and the like.

Description

technical field [0001] The invention belongs to a method for processing remains of ashes. Background technique [0002] There have been reports on the processing method of the ashes of the remains. For example, the Chinese patent document (publication number CN1357461) discloses a method of processing the ashes of the remains. Then use photocopying or hand-painting to composite the information and images about the deceased on the surface of the basic porcelain blank, and then carry out the curing treatment of sintering and glazing on the surface; make bone ash china with composite images. Problems with this method: 1. The finished product has poor toughness, high brittleness, brittleness, and is not conducive to long-term storage; 2. The product cannot be machined after molding; 3. The thermal shock resistance is poor, and the cycle at 100°C to 20°C does not exceed 1000 Second, it is not conducive to long-term preservation. Another Chinese patent document (publication numb...
