Abstract
The invention discloses a method for using small-size ceramic waste balls as a cushion layer for sintering a ceramic product, and the invention relates to the technical fields of ceramic balls and sintering. Along with the increase of the demanded quantity of zirconium balls of 0.1 mm and below in the fields of MLCCs and lithium batteries, the quantity of generated waste balls is also increased; aconventional treatment manner is that the ceramic waste balls are treated as solid waste; the utilization value of the ceramic waste balls is greatly reduced; by using the method, the value of wasteis furthest brought into play; the manner of the secondary utilization of the ceramic waste balls of 0.1 mm and below is found; the ceramic waste balls are mainly applied as the cushion layer in a sintering process of the ceramic product; and an experiment proved that the ceramic waste balls are placed between the ceramic product and a load bearing plate, ceramic powder is scattered to be filled between the ceramic waste balls, and the ceramic waste balls and the ceramic powder cooperate to play a supporting role, so that the problems of the deformation and the difficult discharge of an organic matter in glue discharging and sintering processes of the ceramic product can be solved.
Description
[0001] The invention relates to the technical field of secondary utilization of ceramic waste balls, in particular to a method for using small-sized ceramic waste balls as a cushion layer for sintering ceramic products. Background technique [0002] There are many types of ceramic balls, commonly used are alumina balls, zirconia balls, silicon carbide balls, silicon nitride balls, etc. Take zirconia balls as an example: zirconia ceramic balls have the characteristics of high strength, high toughness, high stiffness, good wear resistance, high temperature resistance, corrosion resistance, non-magnetic conductivity, and electrical insulation at room temperature. When the zirconia ceramic ball is at 600°C, its strength and hardness are almost unchanged, and its density is 6.00 , The thermal expansion rate is close to the thermal expansion rate of metal, and can be used in conjunction with metal, suitable for bearings, seals, etc. High-purity zirconia microbeads (TZP Ceramics be...
