“…In a previous paper (Sallaberry et al, 2015) based on a revision of standards and papers published, we studied the development of testing methods for solar receivers which guarantee their reliability and durability under demanding working conditions of high solar concentrating technology. This methodology was proposed after a careful revision of the most relevant and appropriate literature in order to select proper candidates as receivers that could resist high temperatures and high solar concentrated radiations.…”

Materials used as solar receivers in concentrated solar power technology must withstand severe operational conditions caused by concentrated solar radiation. For this solar technology several ceramic material candidates (silicon carbide, porous and dense silicon oxycarbide) have been subjected to thermal shock resistance test by using Fresnel lens, the equipment available, that concentrates the solar radiation more than 2600 times. Fast heating (37 ºCs -1 ) and cooling rates (28 ºCs -1 ) from 100 to 1200 ºC and dwelling time of 10 minutes are employed. The evolution of materials surface has been evaluated during test by spectroscopic methods and both confocal and electronic microscopies. It has been obtained the surface map of each analyzed sample in materials to thermal shock under concentrated solar radiation makes these materials suitable candidates of being used as high temperature solar receivers.

“…Another point that supports this assumption is that the formation of a SiO 2 layer is not found over all the material surface. In any case, the SiOC d material supports the severe conditions of the thermal shock ageing test quite well (rapid heating at 32 °C s −1 and cooling at 27 °C s −1 , from R.T. to 1000 °C, over 100 cycles), and the high temperature test at 1000 °C (100 cycles) [ 17 ], indicating the huge resistance at these experimental conditions and the suitability of SiOC d material as a candidate for high-temperature solar receivers.…”

“…These studies are based on numerical models and predictions which take into account material properties and other characteristics of receiver design as well as ageing factors and should be completed with accelerated ageing tests that can evaluate the receiver behaviour under real operational conditions [ 6 , 7 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The important and not easy issue is to develop testing methods and standards of validation of materials employed for solar energy applications, which is usually limited by solar testing facilities and also characterization methods available within laboratories [ 16 , 17 ]. The first attempts were made by Rojas-Morín and Fernández-Reche [ 11 ] employing a parabolic dish over INCONEL determining both a numerical model and the fatigue mechanical behaviour.…”

“…Based on previous results [ 17 , 18 ], this work proposes the use of SiOC and silicon oxycarbonitride (SiOCN) materials for their potential as high temperature solar receivers. SiOC materials have interesting intrinsic properties such as good resistance to oxidation in harsh environments, high and tunable mechanical properties, low creep, high absorbance, low CTE, in addition to tunable thermal and electrical properties [ 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

The potential application of silicon oxycarbonitride (SiOCN), silicon oxycarbide (SiOC) and silicon oxycarbide–SiC (SiOC–SiC) for photothermal devices such as volumetric solar absorbers has been studied evaluating the response to thermal shock from a Fresnel lens. The accelerated ageing test comprises fast heating (32 °C min−1) and cooling rates (27 °C min−1) from 100 to 1000 °C and dwelling times of 10 min. Porous materials (SiOCNp and SiOCp) failed the thermal shock tests; they were massively degraded by the formation of a large depression in the focus of solar radiation. Dense materials (SiOCd and SiOC–SiCd) withstood 100 cycles of thermal shock ageing tests due to the formation of a protective silica layer. The absorptance values for dense materials remained fairly constant before and after thermal shock tests: from 94.5 to 94.3% for SiOCd and from 93.3 to 93.3% for SiOC–SiCd. These preliminary studies indicate their potential for high-temperature solar receiver applications.

Considering works published in the literature for more than a decade (period from January 2008 till June 2019), this paper provides an overview of recent applications of the so-called “solar furnaces”, their reactors, process chambers and related devices, aiming specifically at the processing of (solid) materials. Based on the author’s own experience, some prospects on future trends are also presented. The aim of this work is to demonstrate the tremendous potentialities of the usage of solar heat for materials processing, but also to reveal the necessity of further developing solar-driven high-temperature technologies (which are required to displace the use of electricity or natural gas). In particular, it is essential to improve the temperature homogeneity conditions inside reaction chambers for materials processing using solar heat. Moreover, new innovative modular systems, practical and flexible, for capture, concentration, control and conduction of concentrated solar radiation are suggested. Solar thermal technologies for the production of electricity, as well as solar thermochemical processes for production of gases or liquids, are outside the scope of this review.
