<p>Provided are a ceramic thermal shielding piece and heat-resistant structure for same, the ceramic piece comprising a fixing part used for fixing to a heated surface, the heat-resistant structure comprising a heated surface and several ceramic thermal shielding pieces covering the heat-resistant structure; the ceramic thermal shielding pieces partially overlap, the fixing part of each ceramic thermal shielding piece being covered by an adjacent ceramic thermal shielding piece. Ceramic fracture of the ceramic thermal shielding pieces caused by thermal impact and expansion is thus reduced. Furthermore, the partial overlap of the ceramic thermal shielding pieces causes a gap to be formed between the thermal shielding pieces and the heated surface, and slits to be formed in between the thermal shielding pieces; air can pass through the gap and slits, and a film of air can form on the surface of the thermal shielding pieces, providing high-temperature protection for the thermal shielding pieces.</p> |
