Problems solved by technology

[0003] However, the efficiency of the existing isostatic pressing is very low, the energy consumption is large, continuous operation is not possible, and the equipment is dangerous, and the injection molding is fed from one point, which leads to the uneven internal density of the injection molded green body. , there is residual stress, and the product is easily deformed after sintering. At the same time, ball mills are usually used to grind the raw materials in the existing optical fiber preparation process, but the existing ball mills cannot control the temperature during grinding, which will affect the grinding quality and The grinding efficiency makes the grains inside the optical fiber not fine enough, and harmful phase changes are prone to occur during use, which leads to cracking and failure of the sleeve performance

Abstract

The invention relates to the technical field of ceramic materials, and discloses a green preparation process of a zirconia-based metal ceramic material for optical fibers, which comprises the following steps: weighing magnesium nitrate, cerium nitrate, scandium nitrate, calcium nitrate and lanthanum nitrate according to a mass ratio of 1: 2: 2: 0.5: 1, then adding deionized water, and uniformly mixing to prepare a 25% nitrate mixed solution; the metal powder and the alumina-based ceramic powder with the designed amount are taken and placed in a high-speed ball mill to be mixed and ground for 3-5 h, the metal powder and the alumina-based ceramic powder are evenly mixed in a high-speed mixer, and a primary mixture is obtained; according to the green preparation process of the zirconia-based metal ceramic material for the optical fiber, through mixed use of the metal powder and the alumina-based ceramic powder and reasonable control over the pre-sintering heating rate, cracks are reduced, the service life of the optical fiber is prolonged, the grain size of zirconia ceramic is refined through accompanying use of gel precipitation, and the service life of the optical fiber is prolonged. Therefore, the effects of low price, high mechanical strength and excellent anti-aging performance are achieved.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a green preparation process for optical fiber using zirconia-based cermet materials. Background technique [0002] As people's demand for network bandwidth continues to grow rapidly, and governments of various countries are paying more and more attention to information network construction, therefore, telecom operators, radio and television operators, public utilities and some local governments have invested in the wave of fiber-to-the-home construction ; The deployment of fiber-to-the-home requires a large number of optical fibers, optoelectronic devices and transmission equipment, etc., so the construction of fiber-to-the-home has a great demand for fiber optic adapters used in optical distribution frames and optical communication equipment; fiber optic adapters are optical fiber active connectors. Intermediate connection parts; zirconia ceramic sleeve is the core com...
