Effects of different silicon carbide contents on thermal shock resistance properties of mullite-bauxite castable refractory were analyzed respectively by taking the mullite, bauxite as main raw materials and taking calcium aluminate cement as a binding system. After 24 h curing in mould and another 24 h curing at 110° after demoulding, the samples were heated at 1000, 1300 and 1500° for 3 h
A substantial decrease of sheet resistance is measured for AZO films: 86 Ω/ and 61 Ω/ for 5 wt% and 10% doped samples, respectively. Simultaneously, the transmittance of the films is kept high. The average values in the visible range for films with thickness of 200 nm are 86% for undoped ones and 84% and 80% for 5 and 10% Al-doped films, respectively.
Thermal spraying is a process in which a high-temperature heat source is used to melt and accelerate micron-sized metal, silicon carbide, or aluminum oxide, to name a few. For the thermal spraying process, aluminum oxide grit is typically used. projected

Aluminum matrix composites reinforced with more that 50 vol.% of SiC particles were fabried using oxyacetylene thermal spraying. The sprayed material consisted of mixtures of aluminum powder with 60-85 vol.% of SiC particles. To favor the processing of the composite, in some cases, the SiC particles were coated with silica following a sol-gel route. This allowed obtaining as-sprayed samples
