Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation and antibacterial inner wall ceramic brick and a preparation method thereof. Background technique [0002] With the development of science and technology, especially the development of energy, space technology, automobile industry, etc., the requirements for materials are becoming more and more stringent, and it is urgent to develop a new type of high-performance structural material. Silicon carbide ceramics have excellent properties such as high temperature strength, strong oxidation resistance, good wear resistance, good thermal stability, small thermal expansion coefficient, high thermal conductivity, high hardness, thermal shock resistance and chemical corrosion resistance. Therefore, SiC ceramics have been applied in many fields as high-performance structural materials. [0003] But the high covalent bonding and low diffusivity in silicon carbide make ...

AI Technical Summary

Problems solved by technology

[0003] However, the high covalent bonding and low diffusivity in silicon carbide make it difficult to sinter without sintering aids and applied pressure

In the early 1970s, Prochazka and others first used a small amount of B and C as additives to obtain a dense silicon carbide sintered body at 2100 ° C and without any pressure. However, the SiC-B-C system belongs to the category of solid-state sintering and requires higher The sintering temperature (>2100°C) requires high thermoelectric energy consumption, and it is easy to cause coarse grains and poor uniformity, resulting in low fracture toughness and strong crack strength sensitivity

However, the current interior wall brick products still have many shortcomings such as poor heat insulation effect, high water absorption, low strength, easy cracking, etc., and have no environmental protection characteristics, have adverse effects on the human body, and cannot achieve air purification. Completely inconsistent with the development direction of modern wall materials
