As a chemical product, flake alkali has strong corrosiveness. What's the difference between flake alkali and sodium silicate? Next, let's take you to know something about it.

　　1、片堿在常溫下是一種白色晶體，具有強腐蝕性，易溶于水，其水溶液呈強堿性，能使酚酞變紅，性狀是白色半透明片狀固體，是根本化工質料。

　　1. Flake alkali is a kind of white crystal at room temperature. It is highly corrosive and soluble in water. Its aqueous solution is strongly alkaline, which can turn phenolphthalein red. It is a white translucent flake solid and is the basic chemical material.

　　2、片堿是固態氫氧化鈉（NaOH）（結晶體）的商品名（你去買化學試劑，通常不說氫氧化鈉，而是說片堿），氫氧化鈉也俗稱燒堿、火堿、苛性鈉，因另一稱號causticsoda而在香港稱為哥士的。

　　2. Flake alkali is the trade name of solid sodium hydroxide (crystal) (you buy chemical reagent, usually not sodium hydroxide, but flake alkali). Sodium hydroxide is also commonly known as caustic soda, caustic soda and caustic soda. It is also known as Costa in Hong Kong because of its other name, causticsoda.

　　3、片堿廣泛用于造紙、合成洗滌及番筧、粘膠纖維、人造絲及綿織品等輕紡工業方面，農藥、染料、橡膠和化學工業方面、石油鉆探，精粹石油油脂和提煉焦油的石油工業。

　　3. Flake alkali is widely used in papermaking, synthetic washing and light textile industries such as soap, viscose fiber, rayon and cotton products, pesticide, dye, rubber and chemical industries, oil drilling, refined petroleum oil and tar refining.

　　4、以及國防工業、機械工業、木材加工、冶金工業，醫藥工業及城市建設等方面。還用于制作化學品、紙張、番筧和洗滌劑、人造絲和玻璃紙，加工鋁礬土制氧化鋁，還用于紡織品的絲光處，水處理等。

　　4. As well as national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry and urban construction. It is also used in the production of chemicals, paper, soap and detergent, rayon and cellophane, alumina from bauxite, mercerization of textiles, water treatment, etc.

　　片堿與硅酸鈉的區別之處就是其應用行業的區別了，產品的本質不同所需要使用的行業也不大相同。雖然都屬于化工物品，但在本質上還是有著一定的區別的。

　　The difference between flake alkali and sodium silicate is that their application industries are different, and the industries that need to be used for the different nature of products are not the same. Although they are all chemical products, they are different in nature.
