Manufacturing method of aluminum oxide ceramic light-gathering cavity with high reflectivity
The invention discloses a manufacturing method of an aluminum oxide ceramic light-gathering cavity with high reflectivity. Raw materials consist of aluminum oxide powder and an additive, wherein the alumina powder accounts for 95-99.7%, and the additive accounts for 0.3-5%. The additive is magnesium oxide, zirconium oxide and silicon oxide. The reflectivity of the aluminum oxide ceramic is improved by doping the additive, the prepared green body has the characteristics of corrosion resistance, good insulativity, good stability, easiness in cleaning and the like, and the mechanical property ofthe ceramic light-gathering cavity is also improved to a certain extent.
