Barium Fluoride (BaF2) Windows can be used in a variety of applications, such as infrared spectroscopy, due to their wide broadband transmission that extends from the deep ultraviolet to the long-wave infrared. Barium fluoride`s low index of refraction of 1.48 provides high transmission without the need for anti-reflection coatings. Barium fluoride windows can be used up to 800°C in a dry environment, but prolonged exposure to moisture can degrade transmission in the vacuum ultraviolet range. While barium
fluoride windows are less resistant to water than calcium fluoride, BaF2 windows are the most resistant optical fluoride to high-energy radiation, but feature lower UV transmittance. BaF2 has a Knoop hardness of 82.

Soil fertilizer includes various soil fertilizers, mud fertilizers, bad residue fertilizers, bone powder, grass ash, slaughterhouse waste and municipal waste.
1. Smoked soil: Smoked soil is also called smoked fertilizer. It is made of litter, turf, rice root, straw and other fuels. It is made of smoked organic matter-rich clods under suitable temperature and low oxygen. The fat content of the smoked soil is higher than that of the common loam. It is a soil fertilizer with high available nitrogen, phosphorus and potassium. Therefore, it can be used as a base fertilizer and topdressing.
2. Cigarette ash: It is a black powder that is removed from the factory chimney. Containing a large amount of free carbon, the content of nitrogen is higher, reaching about 3.5%, and most of it is ammonium nitrogen. Generally applied to vegetables, sweet potato seedbeds and rice fields.
3. Mud: The fertile mud in rivers, ponds, gullies and lakes is collectively called mud. The composition is more complicated. In addition to containing a certain amount of organic matter, it also contains various nutrients such as nitrogen, phosphorus and potassium. Mud fertilizer can be used as base fertilizer and top dressing. The application of a large amount of mud fertilizer can not only supply crop nutrients, but also thicken the tillage layer, improve the physical properties of the soil, and improve the soil fertility.
4. Grass ash: The ash remaining after burning of crop straw, firewood, litter, etc. is collectively referred to as ash. Its composition is complex, and the ash elements contained in the plants are found in the ash. However, potassium and calcium are the most abundant, followed by phosphorus, and more for potassium. The plant ash is suitable for various soils other than saline, especially for acidic soils. Can be used as base fertilizer and top dressing. Mix 2-3 times with wet soil before application, or use a small amount of water to wet the ash.
