Choosing a Suitable Flux A wide variety of fluxes have been employed for the growth of oxide crystals. These are summarized in Table n. A suitable flux must have  [Pg.234]

Relatively low melting point. (Crystals must grow below the decomposition temperature of the desired phase.) [Pg.234]

Other features such as low volatility, low reactivity with container materials, high purity, and low toxicity are also desirable. [Pg.234]

Fluxes vary in characteristics such as degree of covalency, acid-base characteristics and redox behavior. While chemical reasoning may provide some insights into appropriate choices of suitable fluxes, an empirical approach to the problem is usually necessary to produce crystals of a new compound. [Pg.234]

In the flux-growth method, crystals of the desired ceramic are precipitated from a melt containing the components of the product phase, often in addition to additives used to suppress the melting point of the flux. These additives remain in solution after crystal growth is complete. Crystals are precipitated onto seeds by slowly cooling the melt or the seed, or occasionally by evaporating volatile components of the melt such as alkaH haHdes, depressing the solubiHty of the product phase. [Pg.338]

Thus, we felt it particularly worthwhile to try to improve the preparation of KTP since we were willing to make the bet that drastically improved new materials were not just around the comer. Two KTP preparation methods are in general use, anhydrous flux growth as described by Loiacono and his co-workers 40) and by Ballman 41) and relatively high temperature hydrothermal growth as perfected by Belt and his colleagues. 42) We will not attempt a historical review of the development of these methods. Instead we will outline some features and preparative improvements 43,45) which we discovered as a result of a preliminary study of the process physical chemistry of hydrothermal KTP growth. [Pg.426]

There were some attempts to estimate acid-base properties for oxide compounds, both solids and melts. The most popular of them is Lux-Flood s acid-base theory.2,3 This concept seems to be more effective for estimating the acid-base characteristics of anhydrous borates and of some promising solvents for the flux growth of borate crystals. According to Lewis-Lux s equation,... [Pg.98]
