Abstract: PURPOSE:To obtain a single crystal to be used as a laser medium for an oscillator which is small in size, simple in construction and is capable of oscillating a green laser by incorporating neodymium ions and scandium ions into a lithium niobate single crystal. CONSTITUTION:This lithium niobate single crystal contains 0.01 to 1.2wt.% neodymium ions and over 0.5 to 2.0wt.% scandium ions. Concn. extinction is significant and is undesirable if the neodymium canon. is higher than this range. Crystallinity degrades if the scandium ion concn. is higher than this range. Prescribed ratios of the raw material of the lithium niobate single crystal, such as lithium carbonate and neodymium oxide, etc., which form a congruent compsn. are mixed and the mixture is molded to a green compact in order to obtain such single crystal. The lithium niobate single crystal contg. the neodymium ions and scandium ions is obtd. therefrom by using a pulling up method, such as Czochralski method, a floating zone method, etc.

IPC: C22B4/00
Filed: 1994-05-06
Abstract: PURPOSE: To easily control the carbon balance in a silicon smelting furnace by adopting the Ca yield in recovered silicon as an index at the time of supplying a mixture composed of SiO 2 , carbon source and Ca source to the furnace, heating and reducing the SiO 2  to silicon.  
     CONSTITUTION: The silicon is formed by supplying the mixture composed of the silicon dioxide, carbon source and Ca source to the furnace and causing a carbon heat reduction of the silicon dioxide by a heat treatment. The Ca concn. in the silicon is controlled to a range of 0.4 to 2 wt.% and the formed silicon is recovered from the furnace. The Ca yield in the recovered silicon is measured and the carbon balance of the furnace is determined. Namely, the Ca yield below 80 wt.% indicates that the carbon balance in the furnace is negative and the Ca yield higher than 90 wt.% indicates that the carbon balance in the furnace is excessive. The Ca yield within a range of 80 to 90 wt.% indicates that the carbon balance in the furnace is attained. If the Ca yield is below 80 wt.% or higher than 90 wt.%, the carbon balance of the silicon smelting furnace is controlled by regulating the carbon balance in the furnace.
