[0124] Preparation Example 1. Magnesium Fluoride (MgF 2 ) Preparation of precursor
[0125] By adding 203.3g magnesium chloride (MgCl 2 ·6H 2 O) be dissolved in 5L ion-exchanged water to prepare magnesium chloride aqueous solution, and by 188.26g potassium fluoride (KF 2H 2 O) Dissolve in 5L ion-exchanged water to prepare potassium fluoride aqueous solution. 10 L of ion-exchanged water was added to a 50 L reactor, and an aqueous magnesium chloride solution and an aqueous potassium fluoride solution were simultaneously added to the reactor at a rate of 10 ml / sec while vigorously stirring. Then, the mixture was concentrated using a vacuum concentrator until the volume of the mixture reached 2 L. The concentrated solution was aged by heating at 95°C for 24 hours to prepare a gel. Then, the electrolyte was removed from the gel using an ultrafiltration membrane, and the resultant was concentrated again using a vacuum concentration device until the volume of the mixture rea...

[0126] Preparation Example 2. Sodium Magnesium Fluoride (NaMgF 3 ) Preparation of precursor
[0127] Sodium magnesium fluoride (NaMgF) dispersed in diethylene glycol was prepared in the same manner as in Preparation Example 1 3 ) precursor, except that an aqueous sodium fluoride solution prepared by dissolving 126 g of sodium fluoride (NaF) in 5 L of ion-exchanged water was used instead of an aqueous potassium fluoride solution.

[0128] Preparation Example 3. Silica-magnesium fluoride (SiO 2 -MgF 2 ) Preparation of precursor
[0129] By adding 203.3g magnesium chloride (MgCl 2 ·6H 2 O) Dissolving in 5L of ion-exchanged water to prepare an aqueous solution of magnesium chloride, preparing an aqueous solution of silica sol by diluting 300 g of silica sol (10% by weight, average particle diameter: 5 nm) in 5 L of ion-exchanged water, and preparing an aqueous solution of silica sol by dissolving 74.08 g of ammonium fluoride (NH 4 F) Dissolving in 5L ion-exchanged water to prepare ammonium fluoride aqueous solution. The prepared aqueous silica sol solution was added to a 50 L reactor, and the magnesium chloride aqueous solution was added to the reactor at a rate of 10 ml / sec while vigorously stirring. Then, 300 g of a 0.1N hydrochloric acid solution was added thereto. Then, an aqueous solution of ammonium fluoride was added to the reactor at a rate of 10 ml / sec. Then, a silica-magnesium fluoride...
