| 隨著固體廢棄物排放量的日益增加，已經(jīng)對(duì)環(huán)境造成了極大的危害。開(kāi)展固體廢棄物的減量化、資源化和高附加值綜合利用研究成為許多學(xué)者的重要研究?jī)?nèi)容，同時(shí)也是我國(guó)發(fā)展循環(huán)經(jīng)濟(jì)、實(shí)現(xiàn)可持續(xù)性發(fā)展的必然趨勢(shì)。固體廢棄物含有制備玻璃陶瓷所需主要成分的基礎(chǔ)上，還呈現(xiàn)類似玻璃體微觀結(jié)構(gòu)，使成功制備礦渣玻璃陶瓷成為可能；礦渣特種玻璃陶瓷，是以低品位固體廢棄物為主要原料經(jīng)過(guò)高溫融化、成型、熱處理而制成的一類晶相與玻璃相結(jié)合的復(fù)合材料。具有機(jī)械強(qiáng)度高、熱膨脹性能可調(diào)、耐熱沖擊、耐化學(xué)腐蝕、低介電損耗等優(yōu)越性能被廣泛用于機(jī)械制造、光學(xué)、電子與微電子、航天航空、化學(xué)、工業(yè)、生物醫(yī)藥及建筑等領(lǐng)域。礦渣玻璃陶瓷由于附加值高、配料組成寬、有害物質(zhì)固化效果好等優(yōu)點(diǎn)一直是固體廢物材料化利用領(lǐng)域關(guān)注的熱點(diǎn)。由于傳統(tǒng)能源方法制備的玻璃陶瓷存在生產(chǎn)周期長(zhǎng)，能耗大，成本高等缺點(diǎn)，使得玻璃陶瓷的工業(yè)化生產(chǎn)未能充分實(shí)現(xiàn)。而微波新能源以其獨(dú)特的加熱原理和特點(diǎn)受到廣泛關(guān)注，微波熱源較傳統(tǒng)熱源具有升溫速度快、燒結(jié)時(shí)間短、組織結(jié)構(gòu)可控、節(jié)能環(huán)保等特點(diǎn)，在陶瓷材料的研究和生產(chǎn)領(lǐng)域得到廣泛的應(yīng)運(yùn)并發(fā)揮著重要作用，因此將微波處理技術(shù)引入礦渣玻璃陶瓷的制備過(guò)程具有應(yīng)用和研究雙重意義。 |

| Increasing discharge of solid waste has caused enormous harm on environment. Many scholars have focused on the study of solid waste on reduction, resource and comprehensive utilization of high value-added, also it’s inevitable trend to develop circular economy and achieve sustainable development. |

The ever-increasing disposal of solid wastes has imposed significant hazards on our environment. In this sense, the reduction, reuse and comprehensive utilization (for a high added value) of solid wastes have been the foremost research of many scholars, and is an inevitable trend of our country for developing circular economy and realizing sustainable development. The solid wastes contain the major components for preparing glass ceramics, and display a microstructure similar to that of glass ceramics, which enable the preparation of slag-derived glass ceramics. The slag-derived special glass ceramics, as a kind of composites integrating the characteristics of crystalline phase and glass, are prepared from low-grade solid wastes through high-temperature melting, forming and thermal treatment. They are featured by such merits as high mechanical strength, tunable thermal expansion property, high thermal shock resistance, high chemical corrosion resistance and low dielectric loss, and can be widely applied in the fields of mechanical manufacturing, optics, electronics/microelectronics, aviation, chemistry, industry, biomedicine and construction. As such, the preparation of slag-derived glass ceramics, with the advantages of high added value, wide composition range and good solidification effect of harmful substances, has been a hotspot for the reuse of solid wastes. However, the industrial production of slag-derived glass ceramics is still not sufficiently realized due to long production cycle, high energy consumption and high cost. The microwave-based heat source, compared to other, traditional heat sources, has such advantages as high heating rate, short sintering time, controllable microstructure, low energy consumption and low pollution, and is receiving extensive attention now. Therefore, the introduction of microwave treatment in the preparation of slag-derived glass ceramics is of significant importance to both fundamental research and practical application. 你這個(gè)漢語(yǔ)就有些啰哩啰唆，很多地方寫(xiě)的也不太清楚��！ |
