Abstract

The invention provides a lanthanum-aluminum phosphate composite material. The lanthanum-aluminum phosphate composite material comprises lanthanum phosphate and aluminum phosphate compounded with lanthanum phosphate. The composite material has specific phase composition and micro-structure, and lanthanum phosphate and aluminum phosphate are mutually doped and compounded and bonded through ionic bonds, so that the lanthanum-aluminum phosphate composite material which can be quickly cured and molded at low temperature and has excellent performance at high temperature is obtained. The phosphate composite material provided by the invention can be cured and formed at normal pressure and low temperature, so that the product can be formed without special high-temperature sintering by special equipment, complex high-temperature sintering is omitted in the forming process, and energy is saved. The composite material is excellent in high temperature resistance and good in ablation resistance, the surface of an ablated sample is complete at the ablation temperature of 2000 DEG C, melting does not happen, the preparation process is simple, and the preparation period is short.

Description

technical field

[0001] The invention belongs to the technical field of lanthanum-aluminum phosphate composite materials, and relates to a lanthanum-aluminum phosphate composite material and its preparation method and application, in particular to a lanthanum-aluminum phosphate composite material capable of curing under normal pressure and low temperature and resistant to 2000°C and Its preparation method and application. Background technique

[0002] With the vigorous development of science and technology, many fields (such as aerospace, nuclear engineering and other energy plants) involve extremely high temperature environments. High-temperature heat-resistant materials, as materials used in extreme environments, need to have good high-temperature resistance and other properties, so as to ensure the normal working environment of mechanical components. In order to meet the needs of high-temperature applications, it is of great strategic significance to prepare high-performa...
