Product Description

Borax Acid Powder is widely used in making glass and ceramics glazing

Molecular and crystal structure

The Three Oxygen Atoms Form A Trigonal Planar Geometry Around The Boron. The B-

O Bond Length Is 136 Pm And The O-H Is 97 Pm. The Molecular Point Group Is C3h.

Crystalline Boric Acid Consists Of Layers Of B(OH)3 Molecules Held Together By

Hydrogen Bonds Of Length 272 Pm. The Distance Between Two Adjacent Layers Is

318 Pm.
Based On Mammalian Median Lethal Dose (LD50) Rating Of 2,660 Mg/Kg Body

Mass, Boric Acid Is Only Poisonous If Taken Internally Or Inhaled In Large Quantities.

The Fourteenth Edition Of The Merck Index Indicates That The LD50 Of Boric Acid Is

5.14 G/Kg For Oral Dosages Given To Rats, And That 5 To 20 G/Kg Has Produced Death

In Adult Humans. For Comparison's Sake, The LD50 Of Salt Is Reported To Be 3.75

G/Kg In Rats According To The Merck Index. According To The Agency For Toxic

Substances And Disease Registry, "The Minimal Lethal Dose Of Ingested Boron (As

Boric Acid) Was Reported To Be 2–3 G In Infants, 5–6 G In Children, And 15–20 G In

Adults. However, A Review Of 784 Human Poisonings With Boric Acid (10–88 G)

Reported No Fatalities, With 88% Of Cases Being Asymptomatic."Toxicology

Long-Term Exposure To Boric Acid May Be Of More Concern, Causing Kidney Damage

And Eventually Kidney Failure (See Links Below). Although It Does Not Appear To Be

Carcinogenic, Studies In Dogs Have Reported Testicular Atrophy After Exposure To 32

Mg/Kg Bw/Day For 90 Days. This Level Is Far Lower Than The LD50.

According To The Boric Acid IUCLID Dataset Published By The European

Commission, Boric Acid In High Doses Shows Significant Developmental Toxicity And

Teratogenicity In Rabbit, Rat, And Mouse Fetuses As Well As Cardiovascular Defects,

Skeletal Variations, And Mild Kidney Lesions. As A Consequence In The 30th ATP To

EU Directive 67/548/EEC Of August 2008, The European Commission Decided To

Amend Its Classification As Reprotoxic Category 2, And To Apply The Risk Phrases R60

(May Impair Fertility) And R61 (May Cause Harm To The Unborn Child).

At A 2010 European Diagnostics Manufacturing Association (EDMA) Meeting,

Several New Additions To The Substance Of Very High Concern (SVHC) Candidate

List In Relation To The Registration, Evaluation, Authorisation And Restriction Of

Chemicals Regulations 2007 (REACH) Were Discussed. Following The Registration

And Review Completed As Part Of REACH, The Classification Of Boric Acid CAS

10043-35-3 / 11113-50-1 Is Listed From 1 December 2010 Is H360FD (May Damage

Fertility. May Damage The Unborn Child.

Technical  Indicator

Product  application

1. Glass And Glass Fiber: Boric Acid Granular Is Used To Produce Advanced Glass And Glass Fiber Such As Optical Glass, Acid Resistant Glass, Organic Boron Glass, Etc. It Can Improve The Heat Resistance And Transparency Of Glass, Improve The Mechanical Strength And Shorten The Melting Time.

2. Enamel And Ceramics: Boric Acid Powder Is Used In The Production Of Glaze Compound In Enamel And Ceramic Industry,Which Can Reduce The Thermal Expansion Of Glaze, Reduce The Curing Temperature Of Glaze Compound, Prevent Cracking And Deglazing,And Improve The Luster And Fastness Of Products.

3. Metallurgy: Used As Additive And Cosolvent In The Production Of Boron Steel, So That Boron Steel Has High Hardness And Good Rolling Ductility. Boric Acid Can Prevent Metal Welding, Brazing, Sleeve Welding Surface Oxidation. It Is Also The Raw Material Of Boron Iron Alloy.

4. Leather: Used To Deash The Surface Of Bare Leather To Prevent Gray Spots On The Surface Of Leather After Re-Tanning.

5. Antirust: Boric Acid Can Be Used As Antirust Agent, Lubricant And Thermal Oxidation Stabilizer. It Is Incorporated Into Lubricants, Brake Oils, Metal Working Fluids, Water Treatment Agents, And Fuel Additives.

6. Binder: Boric Acid Is One Of The Ingredients Of Making Corrugated Binder, But Also The Glue Solvent Of Making Cool Protein And Dextrin Binder. Boric Acid Greatly Improves Wet Glue Strength By Cross-Linking The Bonded Hydroxyl Groups.

7. Chemical Industry: Used In The Production Of Various Borates, Such As Sodium Borohydride, Ammonium Hydrogen Borate, Cadmium Borotungstate, Potassium Borohydride, Etc.

8. Other Fields: Dye Stabilizer, Electroplating, Rare Metal Smelting, Electrolytic Capacitor, Paint, Foundry, Textile Industry: Fabric Fire Retardant, Wood Industry: Preservatives, Insecticides, Etc.
