A thermal barrier coating for a component includes an insulating layer applied to a surface of a substrate. The insulating layer comprises a plurality of ceramic microspheres. A sealing layer is bonded to the insulating layer. The sealing layer is non-permeable such that the sealing layer seals against the insulating layer. A method for applying a thermal barrier coating to a surface of a substrate of a component includes providing a plurality of ceramic microspheres and applying the plurality of ceramic microspheres to the surface of the substrate. At least one heat treatment is applied to the plurality of ceramic microspheres on the surface of the component to create an insulating layer on the surface of the substrate.

A method for synthesizing calcium-silicate-based porous particles (CSPPs) is described. Control over CSPP morphology and pore size is achieved through a refined solution-based synthesis, allowing loading of a variety of sealants. These particles, upon external stimuli, release the loaded sealant into the surrounding material. Methods of loading the CSPPs with loading sealant are described. The CSPPs may be used in pure form or mixed with another material to deliver self-healing, sealing and multi-functional properties to a physical structure. The composition of the CSPPs is described, along with methods of use of the CSPPs.

A thermal and environmental barrier coating composed of ceramic hollow microspheres sintered together. In one embodiment the microspheres are sintered together with a powder of another material that acts as a binder, or with a powder of a material that may be the same as the material of the hollow microspheres, forming a matrix in which the hollow microspheres are embedded. The hollow microspheres may be composed of a material with a high temperature capability, and with a low coefficient of thermal expansion.
