✦ Synopsis
It is known that replacing microscopic particles by nano-particles in a composite formulation results in improved physical properties. The authors investigated the possibility adding of nanoparticles SiO 2 and TiO 2 in an amount of 10-30% in the slurry to produce glass-ceramics.
Mechanical strength of the glass-ceramics parts greatly depends on micro-defects of surface and internal structures substantially connected with the factual quality of used production technology, mechanical and heat treatment. There is analyzed a special complex of the destructive and nondestructive methods of strength and quality control of glass-ceramics developed to guarantee the durability of structures used in the usual and extreme service conditions with the temperature up to 1000 ˚C. The methods based on the precise preproduction tests of specimens and real structural elements such as plates and shells were supplemented with the additional non-standard methods for effective use in the working environment which is typical for line production of super thermal-resistant glass-ceramic. As a result of the research found that the adding of nanoparticles in the slurry increases the density of the structure, improves the physical properties and provides high stability of glass-ceramics.
