微波燒結(jié)氧化鋁陶瓷的制造方法是多種多樣的，除了普通粉未常壓燒結(jié)法外，還有熱壓和熱等靜壓燒結(jié)法、Sol-Gel法以及CVD法等，在工業(yè)上，用得多的還是普通粉未常壓燒結(jié)法。
氧化鋁陶瓷的普通粉未常壓燒結(jié)法是在傳統(tǒng)陶瓷制備工藝上發(fā)展起來的，是在干氫或真空條件下進(jìn)行坯體燒結(jié)，這種方法簡單易行，經(jīng)濟(jì)實(shí)用，但保溫時間長燒結(jié)溫度高，且致密程度較低，因而，進(jìn)一步提高透光率受到了限制。
它不是靠外界熱源的幅射、傳導(dǎo)和對流來由外向里加熱坯體，它是利用坯體本身吸收微波能量，從里向外和整體、均勻加熱，因而，熱效率更高、反應(yīng)和燒結(jié)速率更快、燒結(jié)時間縮短和成本降低，并使產(chǎn)品達(dá)到均勻和完全致密化，從而使透過率有所提高。（圖/文www.okcoco.cn）

Alumina ceramics powder sintering method is common in traditional ceramic preparation process developed, in the dry hydrogen or vacuum conditions sinter, this method is simple, economical and practical, but long holding time of high sintering temperature, and dense degree is lower, therefore, further improve the transmission rate by limit.
It is not by an external heat source of radiation, conduction and convection heating the body from outside to inside, it is to use the body itself to absorb microwave energy, from the inside to the outside and overall, uniform heating, therefore, higher thermal efficiency, reaction and sintering rate faster, sintering time and reduce the cost, and make the products reach the uniformly and completely densification, thereby allowing the transmission rate increased.
