红宝石的矿物名称是刚玉，国标规定所谓红宝石即红色的刚玉宝石，它包括了浅红到深

The mineral name of Ruby is corundum. According to the national standard, the so-called Ruby is red corundum, which includes light red to dark

红，所有红色调的刚玉宝石。化学式为A1 20,由于含微量的杂质元素Cr致色而呈红色(其它品种的红颜色宝石不能称作级宝石)。红宝石主要性质为:折射率: 1. 762-1.770，双折率为0. 008-0. 010，密度: 4. 00g/cm'，具典型的吸收谱线，硬度与蓝宝石并排在钻石其后，硬度9，因此只有钻石才能在其表面刻划，用它的一个棱角可以很容易的在玻璃的表面

Red, all red tone corundum gemstones. The chemical formula is A1 20, which is red due to the color of Cr, a trace impurity element (ruby of other varieties cannot be called grade gem). The main properties of Ruby are: refractive index: 1 762-1.770, with a double discount rate of 0.008-0 010, density: 4 00g/cm ', with a typical absorption spectrum, with a hardness parallel to that of sapphire after the diamond, and a hardness of 9. Therefore, only diamonds can be scratched on their surface, and one of its edges can easily be used on the surface of the glass

划出痕迹(玻璃的硬度-般为6以下)，因为红宝石裂理较发育，常见的红宝石其内部有很多的裂纹，即所谓红宝石的“十红九裂”。

The mark is drawn (the hardness of the glass is generally below 6). Because the Ruby cleavage is relatively developed, there are many cracks in the common Ruby, that is, the so-called "ten reds and nine cracks" of Ruby.

红宝石的热处理基本过程是将宝石放置在可控气氛和温度的加热设备中使其中致色离

The basic process of heat treatment of Ruby is to place the ruby in a heating device with controllable atmosphere and temperature to cause color separation

子的含量、价态和晶体结构等发生变化，进而去除蓝色成分，形成和获得更好的红色。这种方法历史悠久，其结果稳定、持久而被人们所接受。

The content, valence state, and crystal structure of the particles undergo changes, thereby removing the blue component and forming and obtaining a better red color. This method has a long history, and its results are stable, long-lasting, and accepted by people.

红宝石的充填处理过程是在真空和加热条件下完成，使充填物质以玻璃态或液态浸人红宝石裂隙中，在充填过程中可以加入一些着色剂，充填处理的红宝石填补了裂隙和空洞掩盖了红宝石的瑕疵，使之颜色更加鲜艳。这种方法其结果相对较稳定，但也不被人们接受。红宝石的表面扩散处理基本过程是用化学方法在颜色浅的红宝石表面渗人微米级的铬元素，使颜色加深，或者产生星光效果。这种方法其结果稳定，但也不被人们接受。

The filling process of Ruby is completed under vacuum and heating conditions, so that the filling material can be immersed into the Ruby fissure in glass or liquid state. Some colorants can be added during the filling process. The Ruby filled the fissure and cavity and covered the Ruby defects, making it more colorful. This method has relatively stable results, but it is also not accepted by people. The basic process of Ruby surface diffusion treatment is to use chemical methods to infiltrate micron level chromium on the surface of Ruby with light color to deepen the color or produce starlight effect. This method has stable results, but it is also not accepted by people.

国家标准《CB/T16552- -2003珠宝玉石名称》中做出明确规定:红宝石进行热处理定为优化，而浸有色油、染色处理、充填处理、表面扩散均定为处理。

The national standard "CB/T16552-2003 Jewelry and Jade Names" clearly stipulates that heat treatment of Ruby is optimized, while immersion in colored oil, dyeing treatment, filling treatment and surface diffusion are all treated.

热处理是红宝石常用的一种优化处理手段，可以不同程度的改变红宝石的颜色或净度。

Heat treatment is a commonly used optimization treatment method for Ruby, which can change the color or clarity of Ruby in varying degrees.

热处理红宝石通常有二种方法：

There are usually two methods for heat treatment of Ruby:

①将颜色为紫红、玫瑰红或粉红色的天然“红宝石”在氧化条件下，加热到1600℃-1700℃,使成份中的Fe“离子(蓝色色素离子)转变为Fe”离子。以消除红宝石中的蓝色调，使其转化为颜色纯正的红宝石。

① The natural "Ruby" with the color of purple red, rose red or pink is heated to 1600 ℃ -1700 ℃ under the oxidation condition, so that the Fe "ion (blue pigment ion) in the composition can be converted into Fe" ion. To eliminate the blue tone in Ruby and turn it into pure Ruby.

②将质量较差的含有丝状包裹体红宝石,加热至1600"C- 1900C,在还原条件下，长时间加热(通常为几个月),使包裹体熔融并同红宝石组成固溶体,然后迅速冷却可去除丝状包裹体。从而提高红宝石的透明度;增强颜色，云雾状的缅甸红宝石多用此法处理间。

② The poor quality Ruby containing filiform inclusions is heated to 1600 "C -1900C. Under the reduction condition, it is heated for a long time (usually several months) to melt the inclusions and form Solid solution with Ruby, and then cooled rapidly to remove the filiform inclusions. Thus, the transparency of Ruby is improved; and the color is enhanced. This method is often used in the processing room for cloud like Myanmar Ruby.
